Effect of pre-existed austenite on austenite reversion and mechanical behavior of an Fe-0.2C-8Mn-2Al medium Mn steel
TL;DR: In this paper, a quenching-Austenite Reversion Treatment (Q-ART) is used to process an Fe-0.2C-8Mn-2Al (all in wt.%) medium Mn steel to investigate the effect of pre-existed austenite on austensite reversion and mechanical properties.
Journal ArticleDOI
Chemical boundary engineering: A new route toward lean, ultrastrong yet ductile steels.
Ran Ding,Yingjie Yao,Binhan Sun,Geng Liu,Jianguo He,Tong Li,Xinhao Wan,Zongbiao Dai,Dirk Ponge,Dierk Raabe,Chi Zhang,Andrew Godfrey,Goro Miyamoto,Tadashi Furuhara,Zhigang Yang,Sybrand van der Zwaag,Sybrand van der Zwaag,Hao Chen +17 more
TL;DR: A unique chemical boundary engineering (CBE) approach is deployed, augmenting the variety in available alloy design strategies, which enables a material with an ultrafine hierarchically heterogeneous microstructure even after heating to high temperatures.
Journal ArticleDOI
A general mixed-mode model for the austenite-to-ferrite transformation kinetics in Fe–C–M alloys
Hao Chen,Sybrand van der Zwaag +1 more
TL;DR: Using the Gibbs energy balance (GEB) concept, a concise GEB model assuming a planar interface is proposed to study the austenite-to-ferrite transformation kinetics in Fe-C-M alloys as discussed by the authors.
Journal ArticleDOI
Fundamentals and application of solid-state phase transformations for advanced high strength steels containing metastable retained austenite
Zongbiao Dai,Hao Chen,Ran Ding,Qi Lu,Chi Zhang,Zhigang Yang,Sybrand van der Zwaag,Sybrand van der Zwaag +7 more
TL;DR: In this paper, the authors provide a brief review of the desired microstructures for Transformation-induced plasticity (TRIP), Carbide-free Bainitic (CFB), Quenching & Partitioning (Q&P), and Medium Manganese steels followed by comprehensive discussions on the phase transformations to be used in their creation.
Journal ArticleDOI
Application of cyclic partial phase transformations for identifying kinetic transitions during solid-state phase transformations: Experiments and modeling
TL;DR: A series of cyclic partial phase transformation experiments has been performed to investigate the growth kinetics of the austenite to ferrite phase transformation, and vice versa, in Fe-Mn-C alloys.
