摘要/Abstract

摘要： 对加热至1100 ℃的中碳富硅合金钢进行了水冷与炉冷两种方式的预处理,并重新加热至930 ℃,然后分别在260 ℃(亚Ms温度)与320 ℃(Ms点以上)两个温度进行等温淬火处理。使用扫描电镜、X射线衍射仪、拉伸与冲击试验等手段研究了奥氏体晶粒细化与等温温度对中碳无碳化物贝氏体钢组织与力学性能的影响。结果表明,水冷预处理态试验钢重新奥氏体后晶粒尺寸约为55 μm,远远低于炉冷预处理态再奥氏体化晶粒尺寸(约155 μm)。由于原始奥氏体晶粒尺寸的减小,相较于炉冷态试验钢,水冷态试验钢等温淬火后贝氏体板条细化,块状M/A岛尺寸变小但数量增加。对于水冷与炉冷两种预处理态试验钢,亚Ms点等温淬火可明显细化M/A岛尺寸,因而具有更高的强塑积与冲击性能。

Abstract: A medium carbon silicon-rich alloy steel was pre-treated by water cooling and furnace cooling respectively from 1100 ℃, reheated to 930 ℃ and then austempered at 260 ℃ (below Ms) and 320 ℃ (above Ms) respectively, by which the effects of austenite grain refinement and isothermal quenching temperature on the microstructure and mechanical properties of the medium carbon carbide-free bainitic steel were studied by means of scanning electron microscope, X-ray diffractometer, tensile and impact tests. The results show that the grain size of the water quenching pre-treated tested steel after re-austenitizing is about 55 μm, which is much smaller than that of the furnace cooling pre-treated tested steel (about 155 μm). Due to refinement of the prior austenite grains, compared with the furnace cooled tested steel, the bainite lath of the water cooled tested steel is refined after isothermal quenching, and the size of blocky M/A islands becomes smaller but the number increases. For both the water cooled and furnace cooled tested steels, below-Ms isothermal quenching can significantly refine the M/A islands size, and thus obtaining a higher strength-elongation product and impact properties.

Key words: carbide-free bainitic steel, grain refinement, isothermal quenching, microstructure, mechanical properties
