Abstract

We performed high-throughput in situ electrical resistance measurement experimentation to understand the effect of cooling rate on the phase transformation behaviour of Ti–5Al–5Mo–5V–3Cr β-Ti alloy. The results suggest the presence of two α-phase variants and that the formation of α-phase starts with a cooling rate of 0.5 °C/s. A slow cooling rate (0.1 °C/s) can be used to obtain similar microstructure and hardness (∼430 Hv) than fast cooling followed by an ageing treatment.
