Notes:
Rolling texture of α"(C-orthorhombic) martensite phase in Ti-22mol%Nb-3mol%Alβ-titanium based shape memory alloy was examined using X-ray pole figure measurement. The alloywas dual phase of α'' and β(bcc) at room temperature (RT) and was cold-rolled with reduction rates of40%~99% at RT. Stress-induced martensitic transformation occurred during the rolling and then thematerial was fully transformed into martensite phase. Subscript α" and β indicate martensite andparent phase hereafter. The major texture was close to {411}α"〈173〉α" when the reduction rate waslower than 60%. This texture is a result of a preferential formation of specific variants which have ahigher interaction with the macroscopic deformation. As the reduction rate was increased, ND movedtoward {101}α" whereas RD was around 〈010〉α" regardless of the reduction rate. {101}α"〈010〉α"texture was confirmed when the reduction rate was 99%
