摘要：
Notched tensile strength (NTS) of the Ti-6Al-4V (Ti-6-4) to Ti-6A16V-2Sn (Ti-6-6-2) dissimilar laser yields were determined, which had been subjected to post-weld heat treatment (PWHT) over the temperature range of 482-704 degrees C. The results indicated for the weld with the PWFIT at 482 degrees C the fusion zone (FZ) and heat-affected zone (HAZ) showed a peak hardness, as compared with other welds at the counterpart regions, whereas, the weld with the PWHT at 704 degrees C had the lowest hardness among the welds. In all the welds, the FZ of the weld subjected to PWHT at 482 degrees C possessed the lowest NTS, while the as-welded and the weld with PWHT at 704 degrees C had superior NTS to others. The presence of grain boundary alpha, which promoted grain boundary shear, accounted for the typical features of mainly transgranular fracture with intergranular dimples of the welds.
