Anomalous Phase Transformation from Martensite to Austenite in Fe-13%Cr-4%Ni-Mo Martensitic Stainless Steel

Yuanyuan Song Xiuyan Liy Lijian Rong Yiyi Li

材料科学技术(英文)

The thermal stability of the reversed austenite in a low carbon Fe-13%Cr-4%Ni-Mo (in wt pct) martensitic stainless steel was investigated by X-ray diffraction (XRD) and superconducting quantum interference device (SQUID) magnetometer. Different amount of the reversed austenite was obtained by contro...

Effect of strong magnetic field on isothermal transformation of degenerate pearlite in an Fe-C-Mo alloy

Zhenni ZHOU

金属学报(英文版)

The pearlite transformation in a Mo-containing iron alloy was investigated under 12~T magnetic field. The pearlite transformation was accelerated owing to the application of a strong magnetic field. Pearlite was of degenerated morphology without the presence of a strong magnetic field; but the degen...

Corrosion Behaviors of Two Types of Commercial Stainless Steel after Plastic Deformation

Esmaeil Jafari

材料科学技术(英文)

The influence of deformation temperature, strain rate and alloying elements such as chromium, nickel, copper, on corrosion resistance of a 304 stainless steel after plastic deformation was investigated. The techniques employed were tensile test at room and elevated temperature, deep drawing tests at...
