Özet

Variation of the sizes and chemical compositions of martensite plates in the structure of powder-metallurgy shape memory alloy Fe - 14 wt.% Mn - 6 wt.% Si - 9 wt.% Cr - 5 wt.% Ni is studied. Apart of the specimens is fabricated from mechanically alloyed powder. Tensile tests of the alloy are performed after 4% deformation and after deformation and heat treatment at 700 and 1100 degrees C. The effect of the treatment on the structure of the alloy is determined.
