Defect analysis of complex-shape aluminum alloy forging SHAN De-bin(单德彬), ZHANG Yan-qiu(张艳秋), WANG Yong(王 勇), XU Fu-chang(徐福昌), XU Wen-chen(徐文臣), L? Yan(吕 炎) School of Materials Science... aluminum alloy with complex shape. The complexity of forging is easy to lead to the occurrence of the defects, such as underfilling, folding, metal flow lines disturbance and fibre breaking. The reasons......
, contact angle measurements and zeta potential tests. The microflotation experiments showed that both depressant agents decrease the flotation recovery of calcite significantly. In addition, sodium carbonate acts as activator agent for pyrolusite, and increases its floatability. The flotation experiments and contact angle measurements indicated that the selective depression effect of sodium carbonate......
High Strain Rate Superplasticity in a Micro-grained Al-Mg-Sc Alloy with Predominant High Angle Grain BoundariesF.C. Liu 1,2) , Z.Y. Ma 1) and F.C. Zhang 2) 1) Shenyang National Laboratory...-Mg-Sc exhibited enhanced superplastic deformation kinetics compared to that predicted by the constitutive relationship for superplasticity in fine-grained aluminum alloys. The origin for enhanced......

of profile and the two ends of part with thickness of 10 mm. The profile presents a twisting-type distortion across the cross-section under non-uniform cooling and the maximum twisting angle during quenching is 2.78°. Key words: aluminum profile; unequal and large thicknesses; water quenching; heat transfer coefficient; thermo- mechanical coupling model 1 Introduction Aluminum alloys are widely applied......
