Microstructural evolution and phase transformation in twinning-induced plasticity steel induced by high-pressure torsion
The microstructural evolution of twinning-induced plasticity steel during high-pressure torsion (HPT) processing at 573 K was systematically evaluated. Due to the high processing temperature, the formation of a homogeneous nanostructure was primarily dominated by complicated dislocation and grain boundary activities in lieu of deformation twinning. Apart from the grain refinement process, phase...
متن کاملPlastic strain due to twinning in austenitic TWIP steels
Twinning induced plasticity steels are austenitic alloys in which mechanical twinning is a prominent deformation mode, and which exhibit exceptional combinations of ductility, work hardening and ultimate strength. The authors develop in the present paper a crystallographic theory to enable the quantitative investigation of the role of mechanical twinning in enhancing the properties of these all...
متن کاملTwin-Induced Plasticity of an ECAP-Processed TWIP Steel
The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult. Up to now, this has only been achieved at warm temperatures (above 200 C). In this paper, a FeMnCAl TWIP steel has been processed at room temperature and the resulted microstructure and mechanical prop...
متن کاملObservation of Stacking Fault Tetrahedral in TWIP Steel
Low stacking fault energy face centered cubic (FCC) materials contain characteristic defect structures. Stacking fault tetrahedral are one of those rare structures that occur under special experimental conditions. For the first time, stacking fault tetrahedral were observed in Fe-30Mn-3Al-3Si twinning induced plasticity (TWIP) steel. Their presence resulted from a quenching heat treatment.
متن کاملAn investigation on full annealing temperature and annealing twins’ Density in Fe-33Mn-3Si-2Al high-manganese steel
Twinning induced plasticity (TWIP) steels with high manganese percentage (17-35%), are mostly used in automotive bodies. Their microstructure at room temperature is austenitic, and due to the low stacking fault energy, major deformation mechanism in them is twinning inside austenite grains which leads to enhanced mechanical strength in the steel. Due to the important effect of heat treatment pr...
