Texture Formation in Thin Tapes from Ni-based Ternary Alloys with Cr, W, Mo and V

摘要

Texture, structure, and magnetic and mechanical properties of thin tape substrates fabricated of ternary nickel alloys with chromium, tungsten, molybdenum, and vanadium have been investigated. It has been shown that in Ni_(93.8)Cr_(4.0)Mo_(2.2), Ni_(88.5)Cr_(6.2)V_(5.3) and Ni_(88.4)Cr_(9.2)W_(2.4) alloys a sharp cube texture can form, which is stable up to high annealing temperatures. In the Ni_(87.6)Cr_(8.0)Mo_(4.4) alloy, other weak orientations are present, along with the strong cube component. The possibility of obtaining a sharp cube texture after primary recrystallization is controlled by the quantitative relationship between the texture components in a cold-rolled tape, which is determined by the method of orientation-distribution functions. Three alloys studied are non-magnetic at 77 K.
