Mechanism of hot-rolling crack formation in lean duplex stainless steel 2101Zhi-hui Feng,Jing-yuan Li,Yi-de WangSchool of Materials Science and Engineering, University of Science and Technology.... In the rolling process, the ferrite grains of LDX2101 underwent continuous softening and were substantially refined. However, although little recrystallization occurred at the boundaries of austenite......
Fatigue Damage Mechanism of AL6XN Austenitic Stainless Steel at High TemperaturesYanyan Hong1,2,Penglin Gao1,Hongjia Li1,Changsheng Zhang1,Guangai Sun11. Key Laboratory of Neutron Physics,Institute.... The continuous cycle softening behavior was also observed on the fatigue curve at 600 °C, which is considered to be caused by dynamic recovery.关键词:......

EFFECT OF INITIAL GRAIN SIZE ON STATIC RECRYSTALLIZA-TION SOFTENING IN Cr STEEL USING STRESS RELAXATION TECHNIQUE A.R.Morgridge1 (1.Mechanical Engineering Dept. of University of Ibadan, Ibadan, Nigeria) Abstract:Effect of initial grain size (I.G.S.) on static recrystallization softening in Cr steel(0.77wt.% CR) has been investigated through the use of interrupted hot compressiontests......
and its interaction. The strain-softening characteristic at post-peak under 20 MPa is obvious, which is an ideal plastic characteristic. 20 MPa is considered to be the brittle-ductility conversion point... test. The axial strain is about 7.6×10-3 before yielding, and the softening stage does not come until a big plastic deformation appears after yielding, then the macro failure happens at last. Figure 5(b......
