  • 用自催化沉积非晶态(Ni,Cu)100-xPx+SiC复合材料,研究了复合材料的组成与晶化特性,结果表明,当x>14或者SiC体积分数小于12.8%时,复合材料即保持非晶态;时效温度达到603—618K,复合材料逐渐向晶态过渡,晶化相为fc c Ni和NiyPz,稳定组织为(Ni,Cu)P+Ni3P+SiC.较非晶态复合材料,晶态材料具有更高的力学性能.
    The amorphous (Ni,Cu)100-xPx+SiC composites were fabricated by self-catalyzing deposition, and the composition and crystallization characteristics were studied. The results showed that the composites kept at amorphous state when x was more than 14 or the fraction of SiC less than 12.8%; they would transform gradually into crystalline with the increase of aging temperature at 603—618K; and the crystallized phases were fcc Ni and NiyPz respectively; (Ni,Cu)P+Ni3P+SiC was formed as a stable microstructure. Compared with amorphous composites, crystalline materials exhibited higher machanical properties.
