It is considered that this is because the residual strain is removed. Therefore, in this study, the thermal treatment of titanium materials after cold-work was performed at 450℃, and we evaluated whether residual strain removal is possible using X-ray diffraction. As a result of experiments, the following conclusions were made: 1. X-ray diffraction confirmed the presence of residual strain in titanium materials after stamping press. 2. The residual strain in titanium materials after stamping press was decreased by heating at 450℃. 3. The hardness of titanium materials was higher after than before stamping press, and that of titanium materials after stamping press showed a lower value after heating at 450℃ than before heating., application/pdf}, pages = {209--213}, title = {冷間加工したチタン材の残留ひずみに対する熱処理の効果}, volume = {36}, year = {2010} }
