摘要
钽钨合金具有高密度、耐高温、强度高、化学稳定和加工性能好等特点,是航空航天、化学、核工业、高温技术等领域不可缺少的重要材料,具有很好的应用前景。通过研究Ta-2.5W合金的金相组织和力学性能,确定了Ta-2.5W合金的再结晶退火工艺:Ta-2.5W合金锻棒的再结晶退火工艺为1450℃×30min真空退火;Ta-2.5W合金锻棒经过单道次86%的冷变形以后,再结晶退火工艺为1400℃×30min真空退火。
Ta-W alloy possesses many useful characteristics, such as high density, high temperature resistance, high strength, chemical stabilization, good processability, etc. It is a sort of important material for aviation, spaceflight, chemistry, nuclear industry, high temperature technology, etc. Metallurgical phase and mechanical property of Ta-2.5W alloy were investigated, and recrystallization annealing process of Ta-2.5W alloy was ascertained. Recrystallization annealing process of Ta-2.5W alloy forged rod is ...
