The same range of titanium concentrations is used in Al-Ti-B refiners with boron contents from 0.2 to 1% and titanium-to-boron ratios ranging from about 5 to 50. For the cast alloys, this includes the aluminum-copper alloys (2xx.x), some of the aluminum-silicon+copper and/or magnesium alloys (3xx.x), and the aluminum-zinc alloys (7xx.x). I am trying to explain grain direction and need a picture of L, LT & ST to define. 20 … However, this could be factored into design use of the part. Texture or grain direction must be taken into account for accurate predictions of material behavior and characteristics when forming/bending. Cosmetic parts with a 90-degree grain direction may be highly undesirable. Am I correct in stating that for a rectanglar bar, L = Longitudinal or actual grain direction, ST = Short Transverse = Thickness and LT = width. In other words, grain boundaries stop dislocations (see Figure 1). A metal’s strength is directly related to its grain size; reducing grain size is a common way to improve material strength which often has little to no effect on the material’s toughness. If it's plate it has an arrow that marke the grain direction. The most widely used grain refiners are master alloys of titanium, or of titanium and boron, in aluminum. Grain direction is primarily used to make sure the plates do not crack when locked into the lockups on your press..and in all cases grain direction is in relation to the grain of the actual aluminum of the plate, not the EC grain of the coating. It is used during castings, such as die casting or gravity casting, as aluminum can be melted in a variety of ways. More importantly, non-metallic inclusions, particles and other impurities inherited during the casting process are elongated in the direction of grain flow. The grain can be seen by viewing off the shelf sheet and noting the direction of visible lines running end to end. If you want to specify the rolling direction on the sawn material, in the example below it will be 300 mm. Different Types And…. The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. The grain direction is in the rolling direction of the sheet as it was being manufactured. This manufacturing method is where hot metal is compressed through rollers and forced into shape, elongating the crystals in the process.

It means doing something the wrong way.When you’re talking about wood, you always want to go with the grain—cutting or planing a board in a way that follows the natural structure of the tree (Photo 1). So, from time to time we need to show the direction of the grain on sheet metal parts. Grain direction is usually specified on stainless steel and other hard materials when it is necessary to maintain minimum bend radius or to control spring back on parts with large radius forms. Individual grains are elongated in the direction of the metal flow or plastic deformation. Figure 1 shows the grain flow in a forged and machined component. Tensile specimens with 5 mm gage width and 20 mm gage length were machined with the tensile axis parallel to the rolling direction. And, as noted previously, the metal’s grains run parallel to the rolling direction. Then, macro-etching is carried out. As a general rule, the grain line must run perpendicular to the bend to avoid the potential for cracking or fracture. Texture or grain direction must be taken into account for accurate predictions of material behavior and characteristics when forming/bending. Again, the T651 material is the better choice because of the reduced grain structure and more consistent product alloy. Just be sure and handle the parts carefully after graining, as a scratch going against the grain will show up after processing. Like the grain in wood, a metal’s grain affects how the piece behaves. I've never seen sheet metal (aluminum) bought this way, but that may be available also.

The other grain directions for wood result in how the particular board was cut from the tree. Grain flow or direction in metal alloys is not a function of heat treatment but of mechanical deformation. Individual grains are elongated in the direction of the metal flow or plastic deformation. Each is influenced by how the metal deforms, which in turn depends on the metal’… Grain flow occurs to some extent in all metal-forming processes, and not just forging. For aluminium alloy. The grain orientation will obviously effect forming characteristics. In the metallographic laboratory, analyzing grains in metallic and alloy samples, such as aluminum or steel, is important for quality control. Thus, an easy way to improve the strength of a material is to make the grains as small as possible, increasing the amount of grain boundary. For an aluminium alloy, what affects grain size and orientation? Submitting drawings or photographs increases the chances of getting proper quotes, Forging is done by providing compressive forces for metal shaping.

Powered by vBulletin® Version 4.2.5 Posted By" ">Steve on October 18, 2002 at 16:49:54:. Rolling and extrusion leads to a grain orientation parallel to the direction of transformation. Why Forging Flow Lines are visible: One can observe grain flow-lines due to the presence of particles and inclusions. aluminum-lithium alloys of the 8xxx series. More importantly, non-metallic inclusions, particles and other impurities inherited during the casting process are elongated in the direction of grain flow. Q. I have a problem with grain marks on the Aluminium. If extruded stock is used (T6511), the parts can show a definite grain direction. Grain Marks on Etched 6082 Aluminum Surface November 2, 2015. Definition: Forging Flow Lines is a directional orientation of metal grains and any non-metallic inclusions that have been deformed due to forging. More importantly, non-metallic inclusions, particles and other impurities inherited during the casting process are elongated in the direction of grain flow. The fundamental relationships between grain orientation, deformation-induced ... tions of one specimen in the rolling direction of the sheet and one in the transverse direction. Generally, low-carbon-content steel or soft aluminum is necessary for good formability and a tight inside radius; but as the level of carbon in the steel or the hardness of the aluminum increases, its ductility and formability are limited, increasing the minimum radius that can be produced. Two rollers compressing the hot metal cause the polycrystalline material to elongate in the direction of rolling. Your part needs to have a Sheet Metal feature and Flat Pattern feature. How well the metal deals with the expansion and compression (among other factors) determines the amount of unexpected deformation (see Figure 2). stable supply high quality aluminum plate grain direction . A286. The grain flow determines the strength of the metal piece. Aluminum plate (thickness >.250 inch) has three grain orientations, each with their own strength values. The forging needs to be ground and polished, after sectioning, similar to a metallographic sample. New Construction Aluminum Co., LTD (NCA) woods grain Aluminum profile is coated with PVDF fluorocarbon coatings and comes with a great variety of wooden grains for customers to choose from. Grain-boundary strengthening (or Hall–Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size. Definition: Forging Flow Lines is a directional orientation of metal grains and any non-metallic inclusions that have been deformed due to forging. © 2020 Copyright Practicalmachinist.com. Rolling and extrusion leads to a grain orientation parallel to the direction of transformation. There are probably companies in your area that offer this service. Since stress corrosion has an intercrystalline propagation, susceptibility to this type of corrosion is, therefore, not the same in the three directions with respect to the direction of rolling or extrusion ( Figure B.2.13 ): The strongest grain direction is of course, L or longitudinal. It is important to remember that aluminum must be timesaved in the same direction as the grain structure, else it will appear cross-hatched after anodizing. I often tell people that the grain direction in a board is like the fur on a cat. http://www-glast.slac.stanford.edu/M...-spec-522b.pdf, Fabrication: CNC Laser, Waterjet, Plasma, Welding & Fab, Schaublin, Cazeneuve, Weiler, Graziano, Mori Seiki Lathes, Cincinnati Milacron, Kearney Trecker, VN, USA Heavy Iron, Machine Reconditioning, Scraping and Inspection, Tooling, Parts and Accessories For Sale or Wanted, Machinery Manual, Brochure and Photo Archives. In cases where there are multiple bends in different directions, causing the grain line to run parallel with the bend, it is always worthwhile considering your material choice and thickness and also the size of the radius to limit cracking. The result was directional solidification processing in which grain boundaries were eliminated by producing columnar grain structures aligned parallel to the axis of the blade, since this is usually the direction of maximum tensile stress felt by a blade during its rotation in an airplane. The metal is corroded due to acid and the unaffected inclusions are visible as flow lines. Speaking for aluminum alloys alone, think of the grain as being generally shaped like an ellipsoid, with one axis very long relative to the others, and the two other axes almost equal in dimension. Stroke the cat (or board) one way and the cat will purr, and your tool will produce a nice sur-face. It is strong and corrosion resistant, plus it's easy to machine and weld. The optimum alignment occurs when the maximum principal stress (perpendicular to a potential crack or fracture) is aligned with the grain-flow lines.
