不同工艺下低碳马氏体钢的组织与力学性能

研究了淬火温度和保温时间对低碳马氏体钢组织、抗拉强度和屈服强度的影响.结果表明，淬火温度和保温时间对试样的组织和力学性能影响显著；在890℃下保温70和210s淬火试样的组织主要为板条状马氏体和块状铁素体；在920和950℃下保温210s淬火，其组织为板条状全马氏体；在920℃下保温70~210s淬火试样具有良好的力学性能.

Microstructure and Mechanical Properties of Low-Carbon Martensite Steel Under Different Processes

The effects of the quenching temperature and holding time on the microstructure, tensile strength and yield strength of the low-carbon martensite steel were investigated. The research results showed that the quenching temperature and holding time had an obvious influence on the microstructure and mechanical properties of the samples. The microstructures of the samples quenched at 890 °C for 70 s and 210 s mainly consisted of lath martensite and massive ferrite. The whole lath martensite microstructure was observed while quenched at 920 °C and 950 °C holding for 210 s. The sample quenched at 920 °C holding for 70~210 s had good mechanical properties.
