modeling was drawn while the high-temperature deformation mechanism maps incorporating dislocations inside grains were obtained. The processing map was used to analyze the hot deformation behavior and determine the processing instability regime and appropriate processing regimes. Within appropriate processing regime, based on the elevated temperature deformation mechanism maps, the Burgers vector......
Deformation behavior of high performance fiber reinforced cementitious composite prepared with asphalt emulsionHE Rui(何锐)1, 2, 3, CHEN Shuan-fa(陈拴发)1, 3, SUN Wen-juan(孙文娟)4, GONG Rui(弓锐)5(1... observation was conducted to evaluate the contribution of polyvinyl alcohol (PVA) fiber and asphalt emulsion to the composite toughening mechanism. The tests results show that the most remarkable......

activation energy of the alloy is calculated to be 249.8 kJ/mol. The deformed mechanism of HCR alloy during creep is double orientation slipping of dislocations activated within α phase with HCP structure... mechanism of the alloy is the multiple slipping of (1/2) á111? dislocations activated within β phase with BCC structure. In this alloy, the high volume fraction V-riched β phase may enhance the creep......
hardening; deformation mechanism 在汽车轻量化的浪潮中,虽然钢仍然占主导地位,但以轻质结构材料为代表的镁合金,因其密度低,比强度和比刚度高,机加工,阻尼减震和电磁屏蔽性能优异等,是实现汽车轻量化最理想的结构材料.然而,密排六方结构的镁合金由于其结构对称性低,滑移系少,加工性差,特别是室温变形时只有基面滑移系启动,加工性能差,极大限制了镁合金在工业上的应用,因此,提高镁合...; 文献标志码:A Influence of strain rate on compression deformation behavior of AM80 magnesium alloy WANG Bing-jie, GUO Peng-cheng, LI Shi-kang, YE Tuo, CAO Shu-fen, LI Luo-xing (State Key Laboratory......
