Interfacial stability of regenerated moulds against molten ZTC4 alloy

  • 摘要: 从研究再生型壳中几种典型金属离子对铸件表面的污染影响规律入手,通过在型壳材料中添加Al、Nb和Mn等金属元素实际浇铸ZTC4合金(Ti-6Al-4V),探讨不同残留金属在铸造过程中对铸件表面质量、陶瓷/钛合金界面成分、组织形貌及显微硬度等的影响,揭示废弃型壳材料中铸造残留金属对钛合金新铸坯陶瓷/合金界面稳定性的影响规律。结果表明:含Al、Nb和Mn等金属残留的型壳浇铸ZTC4合金,铸件表面外观平整无明显铸造缺陷;相比无金属残留型壳,含残留金属型壳的铸件表面粗糙度明显增加;Al金属残留对型壳与熔融钛合金界面稳定性的影响较小,而Nb和Mn金属残留能明显降低型壳与熔融钛合金的界面稳定性,铸件表面粗糙度可以在一定程度上反映界面稳定性;当型壳中含有Al金属残留时,陶瓷/合金界面处析出Ti5Si3相。
