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
Jingkai Zhang1, Yang Li1, Lai Song1, Weihua Liu1 & Xue Zou1 Abstract This study analyzes the effects of different pouring temperatures and mold temperatures on the crack behavior of NaCl–Na2SO4 composite water-soluble salt cores (WSSC). Firstly, calculate the solid fraction during the solidification process of the salt core using the Newton baseline method. Then predict the sensitivity of the salt core

Raja Singh 4, Paolo Mercorelli 5,*, Edison Gundabattini 6,* and Darius Gnanaraj Solomon 7 Abstract In recent times, there has been an increased demand for electric vehicles. In this context, the energy management of the electric motor, which are an important constituent of electric vehicles, plays a pivotal role. A

In this work, a newly designed ceramic shot sleeve is proposed for reducing porosity and optimizing ESCs. As a result, both porosity
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
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
