Quenching and partitioning martensite-a novel steel heat treatment
TL;DR: In this paper, a novel concept for the heat treatment of martensite, different to customary quenching and tempering, is described, which can be used to generate microstructures with martensites/austenite combinations giving attractive properties.
Journal ArticleDOI
Microstructural Features of 'Quenching and Partitioning': A New Martensitic Steel Heat Treatment
David V. Edmonds,K. He,Michael K Miller,Fernando Rizzo,Amy J. Clarke,David K. Matlock,John G. Speer +6 more
TL;DR: In this article, the microstructure following a new martensite heat treatment has been examined, principally by high-resolution microanalytical transmission electron microscopy and by atom probe tomography.
Book ChapterDOI
Martensite tempering behaviour relevant to the quenching and partitioning process
TL;DR: In this article, the effect of Si and Al alloying on steel tempering behavior was investigated using microanalytical electron microscopy, and the authors determined the compositions of epsilon carbide and cementite and the epsilicon to cementite transition during tempering of quenched Si- and Al-containing high-purity Fe-C alloys.
Book ChapterDOI
Microstructural characterisation of steel heat-treated by the novel quenching and partitioning process
TL;DR: The Quenching and Partitioning (QPQP) process as discussed by the authors has exceptionally high carbon concentration of the austenite fraction, which is decoupled from the decomposition of the bainite.
Journal ArticleDOI
Theoretical Prediction of Structural, Mechanical, and Thermophysical Properties of the Precipitates in 2xxx Series Aluminum Alloy
Xuewei Fang,Yefei Li,Qiaoling Zheng,Jian-Cheng Guo,Yanmei Yang,Weiyun Ding,Chunhui Ma,K. He,Ningning Su,Jingyi Jiang,Xiaoxue Chen,Haoran Wang +11 more
TL;DR: In this paper , a theoretical study for the structural, mechanical, and thermophysical properties of the precipitates in 2xxx series aluminum alloy by applying the widely used density functional theory of Perdew-Burke-Ernzerhof (PBE).
