钛的织构控制方法与力学性能各向异性的研究

On the Texture Controlling Methods and Mechanical Property Anisotropy in Commercially Pure Titanium Sheet

采用三维晶体学取向分布函数（ＣＯＤＦ）法研究了常规冷轧退火、热轧态交叉轧制、冷轧态下换向轧制以及循环相变处理等工艺对工业纯钛板材的织构和力学性能各向异性的影响。结果表明，经常规冷轧退火工艺处理后的钛板材主要织构成分为（２１１６）［２６４１］和（１０１３）［１２１０］等，产生了较强的各向异性。而经循环相变处理后，主要织构组分由［２１１０］

Abstract The influence of cold rolling,cold cross rolling,hot cross rolling and cycle phase transformation processes etc. on texture transition and mechanical property anisotropy in commercially pure titanium (C. P. Ti) sheet was investigated by using the crystallite orientation distribution function (CODF) analysis. The results show that after cycle phase transformation process,the main orientation consists of fibre texture (2110) || ND and (2117) || ND (ND means the sheet normal direction) which
