摘要：
Video recording of the free recovery of “hot shape” (typical for the austenitic domain) in shape-memory alloy Fe – 28% Mn – 6% Si – 5% Cr during heating of specimens with a “cold shape” typical for the martensitic domain is performed. Prior to each measurement the specimens are deformed by caliber bending at room temperature in martensitic condition. The thermomechanical training consists in 10 cycles of bending – heating – cooling. Displacements of the free ends of the specimens are plotted as a function of the temperature and the plots are used to determine the critical temperatures of the reverse martensitic transformation.
