    摘要:

    利用不锈钢管水淬法制备出直径为10mm、钨颗粒体积分数达60%的非晶基复合材料。RXD分析表明,除元素W峰外,没有发现其它晶态相的析出。单轴压缩实验表明,复合材料能大幅度提高非晶合金的塑性应变。对非晶复合材料塑性变形机理进行了讨论。

    Abstract:

    The Zr41.25Ti13.75Cu12.5Ni10Be22.5 bulk metallic glass is reinforced with up to 60 volume percent of tungsten particulate. Samples with 10mm in diameter are obtained when quenching melt contained in stainless steel tube into saturated brine. A characterization based on X-ray diffraction and scanning electron microscopy is presented. Compressive tests were performed for the metallic glass matrix composites and single phase bulk metallic glass. Compressive strain-to-failure increase significantly compared to unreinforced single phase Zr41.25Ti13.75Cu12.5Ni10Be22.5 bulk metallic glass. The results are discussed in term of particulate size and yield strength of the reinforcement.
