Cr12MoV钢的强韧化处理工艺研究
|
摘要
研究了Cr12MoV钢的强韧化处理工艺。采用预先热处理+最终热处理的工艺,观察Cr12MoV钢的材料组织及力学性能,结果表明:经过预先热处理后组织中的碳化物得以球化,多呈细小的短棒状弥散分布;同时材料的韧性也有了一定的提高。采用双重固溶球化+1030℃淬火+400℃/260℃回火工艺可有效改善碳化物的形貌及分布,提高了材料的强韧性。
The strengthening and toughening treatment process of Cr12 MoV steel has been studied in the text. Through pre-heat treatment and final heat treatment process, the microstructure and mechanical properties of the material have been observed. The results show that the carbides in the microstructure have been spheroidized after pre-heat treatment most of which is in thin and short rod-like dispersion distribution. At the same time, the toughness of the material has also improved. The morphology and distribution of carbides have been effectively improved by use of double solid solution spheroidization1030 ℃ quenching and 400℃/260℃ tempering process. Thus in this way, the toughness of the material has been improved.
