形状记忆合金包括各种各样的材料。这些材料表现出独特的性能，包括热（形状记忆效应）和机械（伪弹性）记忆，而这两种特性都取决于固态的马氏体相变和无扩散相变。其主要原因之一是其具有形状记忆性和假弹性，优异的生物相容性和高耐腐蚀性。最受关注的（即使在今天）是Ni-Ti和Ni-Ti-Me体系，其中Me代表另一种合金元素。这本书主要涉及镍钛基材料。这些体系的合金具有长程组织、热弹性马氏体和结晶可逆相变的特点。这本书的重点是制造，传统以及非传统的成形技术。除此之外，还有相变温度测量和显微组织特性评价的既定方法。
Shape Memory Alloys include a wide range of various materials. These materials exhibit unique properties including thermal (shape memory effect) and mechanical (pseudoelasticity) memory, whereas both these characteristics depend on the martensitic phase transformation and diffusion-free transformation of the solid state. One of the main reasons is their attractiveness due to shape memory and pseudoelastic properties, excellent biocompability and high corrosive resistance. The most attention (even today) goes to Ni-Ti and Ni-Ti-Me systems, where Me represents another alloying element. This book covers mainly Ni-Ti based materials. Alloys from these systems have characteristic features of long-range structure, thermoelastic martensite and crystallographic reversible phase transformations. This book is focused on fabrication, conventional as well as non-conventional forming techniques. Among others there are stated methods for transformation temperatures measurement and evaluation of microstructural characteristic.
