摘要：
The effects of quenching temperature on the microstructure and mechanical properties of a cast Fe-B-Ti alloy containing 2.0 wt.% of boron and 1.0 wt.% of titanium were investigated. No clear influence on microstructure has been observed unless the quenching temperature is above 900 degrees C. As the quenching temperature exceeds 950 degrees C, most of the boride networks are broken and a large quantity of irregular borides appears. When the quenching temperature reaches 1050 degrees C, the networks disappear completely. The mechanical properties of the cast Fe-B-Ti alloy begin to improve when the quenching temperature increases. The hardness. impact toughness and bend strength have no obvious change when the quenching temperature exceeds 1000 degrees C. The cast Fe-B-Ti alloy quenching at 1000 degrees C has excellent comprehensive mechanical properties, its hardness, bend strength and impact toughness are 58.3 HRC. 2.39 GPa, 17.5 J cm(-2) respectively.
