Abstract

Abstract

Bismuth tin alloy is thought suitable as a cooling media after comparing it with common low melting point metals. Thus, the maximum cooling rate and corresponding temperature cooling characteristics of bismuth tin alloy at different temperature states were characterized by using a cooling medium characteristic testing instrument. At the same time, a JMatPro software was used to simulate and calculate the variation of alloy density and viscosity values of bismuth tin with temperature. Metallographic observation and mechanical properties measurement was conducted to investigate the effect of quenching process on the microstructure and properties of boron containing steel. The results show that the bismuth tin alloy has stable physical properties and excellent cooling characteristics in the molten state, and can be used as a cooling media for the quenching process. The experimental steel can be achieved the best comprehensive performance after it is quenched in a bismuth tin alloy at 150-200 ℃.
