Embodiment 1
[0098] The experimental steps of this embodiment are as follows:
[0099] S1: Accurately weigh raw materials according to the mass percentage of Ti-6%Al-4%V, and prepare alloy samples by arc melting method under inert gas protection conditions. The alloy sample is about 0.3 cm in diameter.
[0100] S2: Turn on the control system 40, rotate the control rod 93 of the sample feeding device 90, and put the alloy sample on the top surface of the sample feeding rod 91. A quenching medium container 61 is placed at the bottom of the vacuum cavity 80, and a quenching cooling medium 62 is contained in the container. The quenching cooling medium 62 is silicon oil. After the alloy sample is sent to the center of the suspension induction coil 71, the vacuum chamber 80 is evacuated to 2×10 by the vacuum system 10 -5 Pa. Close the vacuum system 10, and backfill the vacuum chamber 80 with inert gas to a standard atmospheric pressure. The inert gas is a mixed gas of argon and helium.
