Retrieving Effective Stress Spectrum of Fatigued Components from Fractographic Quantitative Analysis

WU Huaisheng ZHONG Qunpeng Jiangsu Institute of Technology , Zhenjiang , 212013 , ChinaBeijing University of Aeronautics and Astronautics , Beijing , 100083 , China

材料科学技术（英文）

Under the constant amplitude and pro- grammed loading conditions the fatigued fracture surfaces of 2024-T3 sheet are examined by SEM and TEM.A corrected method,in which the effects of loading sequence are taken into account,has been developed for the retrieval of effective stress spectrum.The parame...

Deformation-induced Microstructures of High-Mn Austenite Steel

Qixun DAI Shupeng HUO Jiangsu Institute of Technology , Zhenjiang , 212013 , China

材料科学技术（英文）

Deformation-induced microstructures of high-Mn austenite steel was investigated by metallography,X-ray diffraction and SEM.The ε-martensite and slip-bands are deformation-in- duced on the{111} planes,and appear as thin straight laths with 60～80° alignment difference be- tween them.It was found that ...
