依据作者在文献[1]提出的公式和计算机模拟方法,研究了Ti-Mo,Ti-Nb,Ti-Mo-Si,Ti-V-Al和Ti-6246等10种二元、三元和实用Ti合金的β→α″马氏体相变的晶体学特征。理论计算结果表明;所研究的各种Ti合金的β→α″相变切变量在0.03070—0.09551之间,马氏体亚结构由内孪晶构成,大部分合金的α″马氏体内孪晶比值在1—4之间,部分合金β→α″相变的体积变化小于0.01.从晶体学上说,这些特征与热弹性马氏体相变类似。
According to the formula proposed by the author [1] and computer simulation, ten kinds of binary, ternary and practical Ti-Mo, Ti-Nb, Ti-Mo-Si, Ti-V-Al and Ti-6246 Ti alloy α → α “martensitic transformation.The theoretical calculation results show that the β → α” transformation shear strength of various Ti alloys studied is between 0.03070 and 0.09551, the martensite substructure By the twins, most of the alloy α “martensite twins ratio between 1 to 4, part of the alloy β → α” volume change of less than 0.01. Crystallographically, these characteristics and the thermal elasticity Martensitic transformation similar.
