Abstract
The mechanical behavior and the physical properties of shape memory alloys (SMAs) considerably depend on their structural state. The current research was devoted to the amorphous-crystalline shape memory composites produced by means of the partial isothermal crystallization from melt-spun ribbons. Previous works revealed that such composites contain amorphous matrix with embedded spherical crystalline inclusions and this structure was simulated in the current study with the help of the simple nucleation and growth model. In addition, some aspects of pseudoelastic behavior of the amorphous-crystalline composites were simulated by means of finite element analysis by ANSYS FEA software. This study revealed that pseudoelastic behavior significantly depended on the volume fraction of crystalline phase in the amorphous-crystalline shape memory composite.
