Novel medium-Mn (austenite + martensite) duplex hot-rolled steel achieving 1.6 GPa strength with 20 % ductility by Mn-segregation-induced TRIP mechanism

Lee Hyungsoo, +6 more
- 01 Apr 2018 - 
TL;DR: In this paper, the authors show favorable effects of the Mn-segregated band, by carefully controlling the composition, size, and shape of austenite in Mn-rich and Mn-lean bands in medium-Mn duplex steels.
Journal ArticleDOI

Novel 1.5 GPa-strength with 50%-ductility by transformation-induced plasticity of non-recrystallized austenite in duplex steels.

Seok Su Sohn, +5 more
- 28 Apr 2017 - 
TL;DR: It is demonstrated how the non-recrystallized austenite can be a metamorphosis in 1.5-GPa-grade steel sheet design by actively utilizing non- Recrystallization region and TRansformation-Induced Plasticity (TRIP) mechanism in a cold-rolled and annealed Fe-Mn-Al-C-based steel.
Journal ArticleDOI

Microstructural evolution of liquid metal embrittlement in resistance-spot-welded galvanized TWinning-Induced Plasticity (TWIP) steel sheets

Lee Hyungsoo, +8 more
- 01 Jan 2019 - 
TL;DR: In this paper, microstructural evolutions of small Zn infiltrations or cracks as well as formation behavior of various intermetallic phases were investigated by detailed micro structural evolutions.
Journal ArticleDOI

Cu addition effects on TRIP to TWIP transition and tensile property improvement of ultra-high-strength austenitic high-Mn steels

Jin Hyeok Choi, +7 more
- 01 Mar 2019 - 
TL;DR: In this article, an austenitic high-Mn TRIP steel was suggested to achieve a good strength-ductility balance, and 1.2µwt.% Cu was added as an element for increasing stacking fault energy (SFE) as well as an Austenite stabilizer to exploit a transition from TRIP to TWIP.
Journal ArticleDOI

Novel dynamic compressive and ballistic properties in 7075-T6 Al-matrix hybrid composite reinforced with SiC and B4C particulates

Min Chul Jo, +7 more
- 01 Oct 2019 - 
TL;DR: In this article, a hybrid Al-matrix composite reinforced with both SiC and B4C ceramic particulates was fabricated to increase the volume fraction of ceramics by a liquid pressing process.
