that the fine γ′ precipitate showed the high morphological stability during water-quenching. Therefore knowledge about the change in γ′ phase in thermal fatigue (the alternate heating/cooling cycle... as a cycle. During thermal fatigue, γ′ precipitates changed typically from cubical to irregular shape after 10 cycles, to complex configuration after 20 cycles and raft-like shape after 30 cycles. The very......
Process of aluminum dross recycling and life cycle assessment for Al-Si alloys and brown fused alumina HONG Jian-ping(洪建平)1, WANG Jun(王 俊)1, CHEN Hai-yan(陈海䶮)2, SUN Bao-de(孙宝德)1, LI Jia-jing(李家镜... by environmentally efficient and friendly methods. Two methods of Al dross recycling which could utilize Al dross efficiently were presented. High-quality aluminum-silicon alloys and brown fused alumina (BFA) were......
introduced during manufacturing processes. Despite the efforts taken to understand the influence of these microstructural heterogeneities on the high cycle fatigue (HCF) behavior of these alloys [11... that the fatigue life prediction referred above is focusing on high-cycle fatigue (require more than 104 cycles to failure) in which materials are subjected to small stresses (below yield stress, YS......
Effect of thermal-cooling cycle treatment on thermal expansion behavior of particulate reinforced aluminum matrix composites CHEN Guo-qin(陈国钦), XIU Zi-yang(修子扬), YANG Wen-shu(杨文澍), JIANG Long-tao... and effect of thermal-cooling cycle treatment (TCCT) on the thermal expansion behaviors of three composites were investigated. The results show that the composites are free of porosity and SiC/Al2O3......
Trans. Nonferrous Met. Soc. China 30(2020) 1249-1266 Effect of nano-sized Al2O3 reinforcing particles on uniaxial and high cycle fatigue behaviors of hot-forged AZ31B magnesium alloy M. DAREINI, A. H... with low applied strain; however, a degradation was observed in the high applied strain region. Unlike AZ31B samples, tensile, compressive and high cycle fatigue behaviors of the composite showed less......
