Structural Changes Caused by High-Temperature Holding of Powder Shape Memory Alloy 66% Fe – 14% Mn – 6% Si – 9% Cr – 5% Ni

  • Published:
Metal Science and Heat Treatment Aims and scope

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.
