视频记录了形状记忆合金Fe - 28% Mn - 6% Si - 5% Cr在加热具有马氏体典型“冷形状”的试样时自由恢复“热形状”（典型的奥氏体域）的过程。在每次测量之前，试样在室温马氏体条件下进行口径弯曲变形。热机械训练包括弯曲-加热-冷却10个循环。试样自由端位移随温度的变化曲线可用于确定反马氏体相变的临界温度。
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.
