摘要： This study investigates the mechanical properties of Al-7Si-0.3Mg (A356) alloy affected by the spinning deformation processing (SDP). The cast structure of the A356 alloy becomes elongated with increasing reduction in thickness. This leads to reduction of casting defects, and refines and distributes the eutectic silicon phase throughout the Al-matrix. The hardness tends to reach a steady value due to the uniformity of the microstructure with the reduction in thickness. The SDP leads to a re-arrangement in the eutectic region, which forces the propagation of cracks through the ductile α-Al phase. The tensile strength and elongation increases accordingly. The improvement on tensile strength and elongation produces the best quality index for A356 alloy. 其他題名： J. of Materi Eng and Perform 出版者： Boston: Springer US 出版日期： 2012-09-01 出處： Journal of materials engineering and performance, 2012-09, Vol.21 (9), p.1873-1878 資源來源： EBSCOhost OmniFile Full Text Select 版權： ASM International 2012 識別號： ISSN: 1059-9495 識別號： EISSN: 1544-1024 識別號： DOI: 10.1007/s11665-011-0089-8 識別號： CODEN: JMEPEG
