- Solution heat treatment and subsequent precipitation aging operations of Ti-6Al-4V alloy were conducted, and erichsen test was performed. Detailed microstructure was carefully observed by light optical microscopy (LOM). Influence of heat treatment on hot-rolled sheet forming of Ti-6Al-4V alloy was investigated. The results showed that the microstructure of Ti-6Al-4V alloy consists of two phases ( - ). The grain size of primary phase augmented and second- phase grew with increasing aging temperature. A relatively high aging temperature of 580 leads to sufficient coarsening of the microstructure. The hardness decreases with increasing aging temperature. However, erichsen value reaches the maximum value of 4.5mm for aging treatment at 580 . Erichsen value increases with increasing aging temperature, this is attributed to the fact that the change of phase from finely dispersed particles to coarsening. The cold-forming properties of Ti-6Al-4V alloy were improved by increasing aging temperature.
