In order to solve this problem we propose a thermal management system for light-emitting diode (LED) lighting with a
Imran Zahid ab, M. Farhan a, M. Farooq a, M. Asim a, M. Imran c Abstract Electronic devices are being used extensively for different applications, where the thermal management of these devices is still a critical challenge due to rapid miniaturization, high heat flux and constantly rising temperature. Phase change materials (PCMs) based thermal management is adopted, but the low thermal conductivity limits their use in temperature-controlled electronic devices. Nano-enhanced phase change materials
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

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

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
