“…(100)[001] cube texture through a combination of hot rolling, warm rolling, and annealing steps similar to that used in Fe-Si alloys. [8,9,10] Because the texture obtained is very sensitive to processing conditions and composition, [7][8][9][10][11][12][13][14][15][16][17] a detailed study was needed to identify deformation processing conditions and texture annealing conditions that could provide {hkl}͗001͘ type texture in Fe-Ga alloys and Fe-Al alloys with high Ga and Al contents of 15 at. pct.…”

The feasibility of obtaining [001] preferred texture in polycrystalline Fe 85 Ga 15 and Fe 85 Al 15 magnetostrictive alloys containing 1 mol pct NbC using a low-cost conventional thermomechanical processing approach is shown in this work. Thermomechanical processing conditions examined consisted of a sequence of hot rolling, two-stage warm rolling at 400°C with intermediate anneal at 900°C and texture anneal in the temperature range of 900°C to 1300°C for time periods up to 24 hours. Textures present prior to and after texture annealing were characterized using orientation imaging microscopy in a scanning electron microscope. In the case of Fe 85 Ga 15 alloy with 1 mol pct NbC, the deformation-induced texture after a two-stage warm rolling consists of mixed {100}Ͻ110Ͼ and {111}Ͻ110Ͼ type partial textures. Texture annealing of the Fe 85 Ga 15 alloy with 1 mol pct NbC at 1150°C for 2 hours changes the texture to a predominant texture that is close to {001}͗100͘. On increasing the annealing time to 24 hours, the texture shifts toward {110}Ͻ100Ͼ. While texture anneal at both 1150°C and 1300°C produces a [001] or near-[001] preferred orientation along the rolling direction in the Fe 85 Ga 15 alloy with 1 mol pct NbC, 1150°C-24 hour treatment was found to provide the strongest [001] orientation among the conditions examined. Similar trends are observed for the case of Fe 85 Al 15 alloy with 1 mol pct NbC.

The room temperature tensile properties of cold-rolled and annealed Fea(A1,Cr,Zr) alloy are similar to those of warm-rolled Fe3A1 alloys. The cold-rolled Fe3(A1,Cr,Zr) alloy is also susceptible to test environments. It has been shown that the ductility in various environments decreases in sequence of oxygen--oil--air--distilled water. The results of X-ray diffraction analysis show that (211) preferred orientation of B2 phase appears in cold-rolled Fe3 (A1, Cr, Zr) alloy after recrystallization annealing.

A material combining low remanence with a low coercive force has been developed by applying a hightemperature heat treatment to alloys in the region of 9 wt % aluminum iron. This material displays a large grain size with a predominantly (111) texture in the plane of the sheet. Epstein strips as well as rings of 9% aluminum iron had a remanence of 1.66 to 2.68 kG and a coercive force of 0.25 to 0.3 Oe. Other typical properties were a maximum permeability of 2700, inductions of 12.9 kG at 10 Oe and 16.1 kG at 100 Oe, electrical resistivity of 90 !'1l-cm, and Rockwell B hardness of 87. The properties of these alloys may be particularly suitable for application in relays, where a low residual induction would minimize or eliminate the air gap and good mechanical properties would reduce the wear of the relay pole faces.
