ANISOTROPY OF THERMAL FATIGUE PROPERTIES OF COLD-ROLLED TINI SHEET

The texture of cold-rolled and heat-treated TiNi sheet has been measur ed and designated as {110}[110BAR]p. This material has been used in th ermal fatigue tests during and after which the anisotropy and developm ent of several thermomechanical properties, such as transformation tem peratures and strains, have been measured. Furthermore, the resulting changes of texture after thermal fatigue are presented. The observed e ffects are explained on the basis of the parent texture and the specif ic, martensite variants that are formed according to the lattice corre spondence between austenite (P) and martensite (M).
