摘要

Microstructures of ZTC4 Ti alloy casting sheets before and after welding repairs were analyzed, and effects of welding repairs on tensile, bending strength and impacting properties of the alloy sheets were investigated. The results show that initial micro-structure of the alloy sheets is changed with the welding repairs. Acicular α' martensite can be observed in the welding zone and heat-affected zone after welding repairs. Although change of tensile strength and bending strength of the alloy sheets can be ignored, elongation and impacting toughness after welding repairs are greatly decreased by 35% and 30%, respectively.
