采用粉末冶金工艺生产了 8 vol.-% SiC 颗粒复合材料增强的 6061 铝合金。比较了使用不同尺寸粉末制成的样品的可压缩性和性能。为了获得高密度样品，MA 粉末在 300–500°C 的氢气下脱气。结果表明，压制前的脱气过程提高了可压缩性和生坯强度，并去除了粉末中的一些杂质。
6061 aluminium alloy reinforced with 8 vol.-%SiC particulate composite was produced by PM processing. The compressibility and properties of samples made using different sized powders were compared. To obtain a high density sample, MA powders were degassed at 300–500°C under hydrogen. The results show that the degassing process prior to pressing improves compressibility and green strength and removes some impurities from the powder.
