as ~3.7 μm.Such a specimen shows an elongation of 642%,and its ultimate fracture surface exhibits intergranular separation and significant grain growth.Additionally,the effects of the specimen’s geometry...Superplastic elongation characteristic of fine grained magnesium alloy ZK60LEE Shyong1,CHIANG Chihte1,LEU Jyhshyan11. Department of Mechanical Engineering,National Central University摘 要:
="ChDivSummary" name="ChDivSummary">Abstract:The strength and elongation to fracture of spray deposited Al-Si-Pb alloys were studied as a function of lead content,silicon content,and distance from the centre to periphery of the deposit.It is found that the ultimate tensile strength,proof stress and elongation to fracture decrease,linearly and exponentially,with the increase in lead content......
corresponds to a stage of fatigue respectively, including crack initiation, slow stable crack growth and rapid fracture. The intersecting point between elongation line of curve in Region I... High cycle fatigue and fracture behavior of 2124-T851 aluminum alloy LI Xue(李雪)1, YIN Zhi-min(尹志民)1, NIE Bo(聂波)1, 2, ZHONG Li(钟利)1, 2, PAN Qing-lin(潘清林)1, JIANG Feng(姜锋)1 1. School of Materials......

in the peak-aged sample tested at 300 ?C, corresponding to the intergranular fracture. Localized plastic deformation at grain boundaries is also observed and corresponds to the high elongation at 300 ?C... approaches. Besides, the fracture behavior is also important in understanding the relationship between microstructure and mechanical properties, as it determines the fracture strength and elongation. However......
