通過(guò)2種方案試制d350 mm Ti-1023合金棒材，分析2種方案生產(chǎn)的棒材橫、縱向組織，力學(xué)性能和探傷結(jié)果的差異。研究結(jié)果表明：鑄錠開(kāi)坯及中間鍛造采用1次“高低高”鍛造，成品鍛造在相變溫度以下35~50 ℃進(jìn)行，變形量大于60%；在該鍛造工藝下，可生產(chǎn)出滿(mǎn)足X/BS5116標(biāo)準(zhǔn)要求的棒材，且棒材的組織均勻性好。

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.
