Aligned Ferrous Martensite.
Abstract
Previous research has shown that an Fe-Ni-Mn alloy may be suitable for producing aligned martensite. This work is concerned with the texture and transformation characteristics of the Fe-20%Ni-5%Mn alloy. The austenitic deformation texture was found to be typical face-centered cubic (fcc) texture--(123) (412) rather than (100) (011) as thought previously. Subsequent annealing at 1000 C for 30 min produced a strong annealing cube texture (011) (100). A partial alignment of martensite was obtained by stress-assisted transformation. Nearly 75 percent martensite was aligned when a strongly cube-textured specimen was strained 3 percent at 45 degrees to the rolling direction, followed by a liquid nitrogen quench of 10 hours.
