of the foam pattern produces a chilling effect in the liquid metal, and this will influence the solidification of the filling metal and microstructure of castings. Currently, the solidification... process of LFC, the existence of the foam makes the heat transfer behaviors of the metal liquid more intricate than that of conventional casting process. On one side, the foam endothermic decomposition......
investigation on thermal performance of metal foam capillary wick heat pipe LI Hongchuan, JI Xianbing, ZHOU Dongdong, XU Jinliang (Beijing Key Laboratory of Multiphase Flow and Heat Transfer, School of Energy... heat pipe(NHP) was designed with ultra-light porous copper foam metal as capillary wick. The effect of heat flux q and inclination angel of heat pipe θ on thermal performance of the NHP was studied using......

metal foam; reticular nickel foam; composite structure for sound absorption; low frequency sound absorption 1 Introduction Noise pollution is a worldwide hazard. To solve this problem, noise reduction...]. Metal foam is one kind of porous materials, which could be applied as effective sound absorption materials. It has both metallic and porous structured properties, and exhibits high strength as well......
Metal Dusting-Mechanisms and Preventions () 摘要:Metal dusting attacks iron, low and high alloy steels and nickel-or cobalt-base alloys by disintegrating bulk metals and alloys into metal particles... mechanism is still not well understood. Current methods of protection against metal dusting are either directed to the process conditions-temperature and gas composition-or to the development of a dense......
Strength and thermal behavior of low weight foam geopolymer using circulating fluidized bed combustion fly ashLIU Ze(刘泽), SHAO Ning-ning(邵宁宁), QIN Jun-feng(秦俊峰), KONG Fan-long(孔凡龙), WANG Chun-xue(王春...:A comparative study of the influence of elevated temperature on foam geopolymer using circulating fluidized bed combustion fly ash (CFA) was reported. Foam geopoymers were prepared with different......
