Investigation of Portevin–Le Chatelier Band Strain and Elastic Shrinkage in Al-Based Alloys Associated with Mg ContentsYulong Cai1,Suli Yang1,Shihua Fu1,Di Zhang2,Qingchuan Zhang11. CAS Key... correlation of the propagative bands. Additionally, the serration amplitude linearly increases with the maximum PLC band strain; high Mg content generates a higher PLC band strain at a given serration......
Texture Evolution, Formability and Ridging Resistance of a Sn-bearing Ferritic Stainless Steel Under Different Hot Band Annealing TemperaturesYang Bai1,Tong He2,Dan Guo1,Xiu-Ting Liu1,Fang-Yuan... stainless steel under different hot band annealing temperatures were investigated. The four hot bands with annealing temperatures of 900, 950, 1000 and 1050 °C were all cold-rolled to 80% reductions......
镁合金热变形下变形带的形貌和晶体学特征杨续跃1,2,姜育培1(1.湖南省长沙市中南大学材料科学与工程学院2.湖南省长沙市中南大学教育部,重点实验室有色金属材料科学与工程)摘 要:对不同温度单向压缩下AZ31镁合金不均匀形变组织的形貌和晶体学特征进行了研究.结果显示:形变组织具有很强的温度和应变敏感性;250℃时,晶粒内在变形初期出现大量的{1012}拉伸孪晶和少数{1011}压缩孪晶,随着应变量的加大,拉伸孪晶因相同取向孪晶的合并而急剧减少,而压缩孪晶明显变粗,数量也有所增加;300℃以上时,非基面滑移被激活后......
Shear band formation in shaped rheocast aluminium component at various plunger velocities M. BLADH1, M. WESS?N2, A. K. DAHLE3 1. Swerea SWECAST AB, Box 2033, 550 02 J?nk?ping, Sweden; 2... in the area of granular materials[10] pointed to a specific relationship between band thickness and grain size, i.e. the bands are 10-20 grains wide. This relationship is seen in controlled rheology......
