Al-enabled properties distribution prediction for high-pressure die casting Al-Si alloy

Al-enabled properties distribution prediction for high-pressure die casting Al-Si alloy

Yu-Tong Yang, Zhong-Yuan Qiu, Zhen Zheng, Liang-Xi Pu, Ding-Ding Chen, Jiang Zheng, Rui-Jie Zhang, Bo Zhang & Shi-Yao Huang Abstract High-pressure die casting (HPDC) is one of the most popular mass production processes in the automotive industry owing to its capability for part consolidation. However, the nonuniform distribution of mechanical properties in large-sized HPDC products adds complexity to part property evaluation. Therefore, a methodology

Effects of Cr-addition on ageing response of an Al–Si–Mg die cast alloy

Effects of Cr-addition on ageing response of an Al–Si–Mg die cast alloy

Yiwu Xu ab1, Yuxin Zhang c1, Jinping Li d, Pan Wang e, Jianfeng Wang e, Houwen Chen c, Houqing Sun f, Hongyi Zhan e Abstract Chromium (Cr) is rarely added to Al–Si die cast alloys as it has a strong tendency to induce the formation of coarse-sized sludge particles. In the present study, high pressure die-cast samples made of Al-7wt.%Si–Cr–Mg alloys with varied Fe contents (0.11 wt%, 0.26 wt% and 0.32 wt%) were tensile tested under as-cast and T5 heat-treated conditions, in comparison

High-Pressure Die Casting of Al–Ce–La–Ni–Fe Alloys

High-Pressure Die Casting of Al–Ce–La–Ni–Fe Alloys

Benjamin E. MacDonald1, Stuart Wiesner2, Ryan Holdsworth1, Carl Söderhjelm1 & Diran ApelianORCID:orcid.org/0000-0001-9743-606X1 Abstract The effects on phase equilibria of La and Fe additions to the Al–Ce–Ni-based alloy system are explored under high-pressure die casting conditions. The addition of La to Al–Ce–Ni-based alloy system only reacts with Ce synergistically to promote the formation of the Al11(Ce,La)3 intermetallic phase as predicted by CALculation

Temperature dependence of mechanical strength in HPDC Mg–6Y–3Zn–1Al alloy with LPSO phase

Temperature dependence of mechanical strength in HPDC Mg–6Y–3Zn–1Al alloy with LPSO phase

Xin Yu a, Yafeng Li b, Yang Bai a, Wei Huang c, Bing Ye a, Xiangyang Kong d Abstract The temperature dependence of mechanical strength including yield strength (YS) and ultimate tensile strength (UTS) in HPDC WZA631 alloy is investigated in a wide temperature range from room temperature (RT) to 350 °C. It is found that at 25–300 °C, YS and UTS do not drop markedly, from 173 MPa and 274 MPa at RT to 113 MPa and 170 MPa at 300 °C, respectively. While

Effect of Thermal Treatment (T5) on Microstructure and Tensile Properties of Vacuum High Pressure Die Cast Al–Si–Mg Alloy

Effect of Thermal Treatment (T5) on Microstructure and Tensile Properties of Vacuum High Pressure Die Cast Al–Si–Mg Alloy

Part of the The Minerals, Metals & Materials Series book series (MMMS) Abstract In this work, a modified Al–Si–Mg (A356) alloy was prepared by vacuum-assisted high pressure die casting processes (V-HPDC). To release residual stresses, various thermal treatment schemes over a wide range of temperatures between 120 and 350 °C were experimented to the as-cast V-HPDC alloy, in
