Transformation During Aging of Niobium-Rich Carbides in Cast Heat-Resistant Alloys

The changes occurring in two heat-resistant alloys while aged at 750 °C for different periods of time were studied. Aging promoted precipitation of secondary M23C6 carbides and transformation of Nb-rich, which were evaluated by SEM. The results …

Multi-dimensional Effect of Heat Treatment on Microstructure and Property of Ti6Al4V Alloy Fabricated by Selective Electron Beam Melting

The as-built Ti6Al4V component was subjected to a heat treatment of solid solution at 1020 °C for 2 hours and followed by aging at 500 °C for 8 hours. The pores in different positions of Ti6Al4V components before and after heat treatment were …
