摘要:

用热膨胀法测量了典型容器用09MnNiDR钢的Ac1和Ac3温度,并用在此基础上设计的淬火工艺对其进行热处理。使用扫描电镜、EBSD和夏比冲击试验机等手段研究了09MnNiDR钢在其厚度方向1/2处的组织、织构和低温冲击性能。结果表明：实验钢的Ac1=692.9℃,Ac3=883.1℃。与“准亚温淬火+回火”或“准亚温淬火+亚温淬火+回火”热处理工艺相比,采用“预淬火+准亚温淬火+回火”热处理,能使09MnNiDR钢板1/2厚度处的低温冲击性能有较大的提高。其原因,一是晶粒的细化,二是织构的漫散分布。

关键词 ：金属材料, 容器钢, 准亚温淬火, 冲击性能, 织构, 晶粒尺寸

Abstract：

The phase transition temperature of Ac1 and Ac3 of 09MnNiDR steel for typical vessel was measured by thermal expansion method, and based on this two new quenching processes were designed. The microstructure, texture and low temperature impact properties of the samples at 1/2 thickness of the plate were investigaed by means of SEM, EBSD and Charpy impact tester. The results show that: Ac1 and Ac3 of 09MnNiDR steel is 692.9℃ and 883.1℃ respectively; compared with the "quasi sub temperature quenching + tempering" or "quasi sub temperature quenching + sub temperature quenching + tempering" heat treatment process, the "pre quenching + quasi sub temperature quenching + tempering" heat treatment could improve the low temperature impact property of the samples at 1/2 thickness of 09MnNiDR steel plate greatly, and one reason of the impact property improvement is grain refinement, another reason is the random distribution of texture.

Key words： metallic materials vessel steel quasi sub temperature quenching impact property texture grain size
