Deformation-induced martensite formation during cyclic deformation of metastable austenitic steel: Influence of temperature and carbon content

Nano/ultrafine grained austenitic stainless steel through the formation and reversion of deformation-induced martensite: Mechanisms, microstructures, mechanical properties, and TRIP effect

“…The phenomenon of transformationinduced plasticity (TRIP) refers to the deformation-induced phase transformation that enhances the work-hardening ability of material, which retards the localized necking and results in the enhanced plastic response [29][30][31][32]. High strain-hardening capacity and high mechanical strength lend TRIP-assisted steels excellent energy absorption capacity, which is essential for many applications, especially in automotive industry.…”

Microstructural changes and strain hardening effects in abrasive contacts at different relative velocities and temperatures

“…The zone up to 10 µm shows many HAGB which can be ascribed to martensite phase transformation. As seen in the phase image (Fig.8-c2), the fine structures relate to deformation induced martensite[40][41][42]. The total area fraction of martensite within the analysed area is 28 %.…”

Martensitic Transformation in Ultrafine-Grained Stainless Steel AISI 304L Under Monotonic and Cyclic Loading

“…In other metastable austenitic steels like CG 301LN, significant martensitic transformation is present already at similar low strains leading to a secondary hardening regime as shown in the studies by Hamada et al [2,20]. On the one hand this behavior can be attributed to the sensitivity of transformation activity to minor changes in chemical composition as the chemical composition influences the probability of the formation of deformation bands [2,[20][21][22]. The results of the present study show that the reduction in grain size reduces the influence of the chemical composition significantly.…”
