摘要
制备出了长径比为 2 5∶1的Zr4 1 Ti1 4Cu1 2 .5Ni1 0 Be2 2 .5大块非晶合金棒 .测定了该非晶合金的热膨胀系数 ,研究了结构弛豫对该合金的硬度和膨胀性能的影响 .通过热膨胀法测定了该非晶合金适合于超塑性变形的温度范围 ,进行了该大块非晶合金的超塑性变形 .
Zr 41Ti 14Cu 12.5Ni 10Be 22.5 bulk amorphous alloy rods with an aspect ratio of 25∶1 were prepared. Thermal expansion coefficient of the alloy was measured. The effects of structural relaxation on hardness and thermal expansion coefficient of the amorphous alloy are studied. A suitable temperature range for super-plastic deformation of the bulk metallic glass is determined by thermal expansion experiments.
