摘要：
The effect of one two-step high-temperature post-weld heat treatment on the microstructure of TC4 weld joints has been studied in our experiment, and as a result, the weld joints with attractive mechanical property have been obtained. The weld joints consisted of lamellar martensitic alpha, retained beta and primary alpha, therefore microstructure of the weld joints would be kept in balance, and spheroidised a phase both in the crystalline grain and grain boundary, which could improve attractive balance of mechanical properties.
