通过2种方案试制d350 mm Ti-1023合金棒材,分析2种方案生产的棒材横、纵向组织,力学性能和探伤结果的差异。研究结果表明:铸锭开坯及中间锻造采用1次“高低高”锻造,成品锻造在相变温度以下35~50 ℃进行,变形量大于60%;在该锻造工艺下,可生产出满足X/BS5116标准要求的棒材,且棒材的组织均匀性好。

The d350 mm bars of Ti-1023 were manufactured by two solutions, the discrepancies of the microstructures in transverse and longitudinal, the mechanical properties and ultrasonic test results of two bars were analyzed. The results show that in the forging processes, i.e., the breakdown of ingot and intermediate forging adopt “high-low-high” at a time, and the forging of finished products is performed at 35−50 ℃ below the transition temperature and the distortion is greater than 60%. The bars produced can meet the mechanical properties in X/BS 5116 with good homogeneity of structure.
