Compression of CuAlNi Crystals

  • L. A. Shepard


Single crystals of beta Cu-14.1Al-3.ONi in (100) orientation were reversibly strained in compression to 18%, and 200,000 psi. Above the Martensite Finish temperature (−11°C), the initial luders band deformation produced a single crystal of (010) oriented gamma prime martensite, the stress level linearly dependent upon temperature. Below −11°C, the martensite itself was reoriented to a single crystal.
