Study on the deformation mechanism of the inflection point in tensile curve of nano/ultrafine-grained Austenite Stainless Steel rolled at different temperature
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2020Co-Authors: Congjie Kang, Kanglin Ye, Jun Tang, Yue MaAbstract:Abstract Nano/ultrafine-grained (NG/UFG) 304 Austenite Stainless Steel can be fabricated through a phase reversion transformation after severe deformation at cryogenic and room temperatures. Here, to understand the deformation mechanisms, a function of rolling temperature was established to determine the typical inflection point of transformation-induced plasticity. The typical inflection point in the tensile curve of annealed NG/UFG 304 Austenite Stainless Steel was found after rolling at room-temperature (RTA) rather than at cryogenic temperatures (LTA). Our results show that tensile deformation of LTA was governed by twin boundaries and a phase reversion transformation compared to RTA. As a result, the increased ultimate strength of LTA can be attributed to the effect of twin boundaries, twin size, and twin quantity on dislocation motion. The presence of twin boundaries suppresses the softening effect induced by martensite transformation.

Corrosion properties of phase reversion induced nano/ultrafine grained AISI 304 metastable Austenite Stainless Steel
Materials Research Bulletin, 2018Co-Authors: Yang Lv, Jinliang Pi, Jun Tang, Kanglin YeAbstract:Abstract AISI 304 metastable Austenite Stainless Steel was cold rolled under cryogenic temperature and transformed into martensite completely, after reverse transformation by annealing, bulk nano/ultrafine grained material was obtained. The material’s microstructure was observed by TEM, and the corrosion resistance was studied by polarization curve, EIS, and Mott-Schottky plot. Results showed that samples cold rolled at −120 °C had an equiaxed microstructure and displayed the best corrosion performance. The distinctive polarization curve shape indicated that its passive film had a peculiar feature, and the M-S plot showed its abnormal semiconductor character. XPS measurements are used to directly characterize the composition of passive film formed on specimens. Heterogeneous microstructures might help with the improvement on corrosion resistance of the nano/ultrafine grained Stainless Steel.
