A new class of W-NiTi heavy alloy was prepared by infiltration and vacuum hot pressing. The W-NiTi heavy alloy containing 90 wt% tungsten of particle size 2-8 gm exhibited excellent tensile properties of the tensile strength (1120 MPa) and elongation (7.8%). In situ synchrotron diffraction experiments provided clear evidence on the reorientation of B19'-NiTi martensite at the initial stage of the deformation and the martensitic transformation from B2-NiTi to B19'-NiTi martensite. Finally, the strain hardening of the heavy alloy resulted from the deformation of the martensite phase and the strain hardening of tungsten particles.
