| 摘 要： | 采用快速压铸法制备了多孔非晶合金。利用NaCl颗粒作为预制型,将熔融的合金倒入卧式压铸机的容杯中进行快速压铸,然后去除盐型,得到直径达40mm、长度大于10mm、孔隙率大于50%、孔隙直径可控制在0.3～3mm之间的(Zr0.55Al0.10Ni0.05Cu0.30)98Er2多孔非晶合金。XRD分析表明所制备的多孔试样组织为非晶结构。采用SEM观察到孔隙之间具有良好的连通性,孔壁厚度小于1mm。热分析结果表明该泡沫的玻璃转变温度、晶化温度和晶化放热量分别为388℃、476℃和-37J/g,与实体非晶合金一致。

| Abstract: | Porous glassy alloys were produced by the method of rapid casting. Porous glassy (Zr0.55Al0.10Ni0.05Cu0.30)98Er2 alloy rods of 40 mm in diameter and 10 mm in length were fabricated by casting (Zr0.55Al0.10Ni0.05Cu0.30)98Er2 liquid into NaCl powders in a few seconds using horizontal die casting machine, followed by leaching treatment into water to eliminate the salt phase. The volume fractions of the pores were evaluated as large as 50%, and the size of pores was changed in the range of 0.3 mm to 3 mm. The r... |
