Abstract

Shape memory alloy Fe - 14Mn - 6Si - 9Cr - 5Ni (wt.%) obtained by cold pressing and sintering of a mixture of powder elements or of mechanically alloyed powder is studied. To compact the alloy additionally the specimens are subjected to hot rolling. Solution treatment of different duration (0.6 - 4.8 ksec) at 1473 K in low vacuum, nitrogen or argon is performed. The structure of the alloy after such treatments is studied by the methods of x-ray diffraction and optical and scanning electron microscopy.
