; Abstract: The CuCr25 and CuCr25Te contact materials were manufactured by vacuum casting process. The microstructures of two alloys were observed by metallographic microscope...-welding property, Te element was added to CuCr alloy. In this work, CuCr25Te alloy was manufactured by vacuum casting process, and its physical property, mechanical property, fractograph and breaking......
[7-9]. Additionally, a new vacuum casting method was suggested by THIAN et al[10]. Many microsystem technologies are limited by materials, size, shaping and high aspect ratio of micro parts prepared... was put into the ceramic crucible and molten in vacuum resistance furnace (GR-20 type). In microcasting a casting temperature of 440 ℃ was used and the holding time was 30 min. The graphite die......
casting process for production of near-net shape castings with high quality. Effect of vacuum on the solidification process and microstructure of LFC magnesium alloy were explored. The results indicate... of the casting during solidification period, and the solidification time of the casting is greater than that without vacuum. The microstructure of LFC magnesium alloy is rather coarse. Compared......
