冷变形对金属玻璃体性能的影响,目前还研究得不多。Chen发现Pd—Cu—Si金属玻璃体没有加工硬化现象。并且他又指出,经冷变形后,金属玻璃的弹性模量大约降低1％。Barmatz等在研究冷变形对Fe-基玻璃滞弹特性的影响时提出,冷变形明显地增强了金属玻璃体在低温时,声波的衰减和散射。Chen用正电子湮没技术研究了冷轧后,Pd—Cu—Si玻璃的结构时提出,冷轧后的金属玻璃体没有产生像空穴缺陷一样的结构。为了解金属玻璃体
The influence of cold deformation on the properties of metallic glass has not been much studied yet. Chen found that Pd-Cu-Si metallic vitreous has no work-hardening. And he also pointed out that after cold deformation, the elastic modulus of metallic glass decreased by about 1%. Barmatz et al., In studying the effect of cold deformation on the hysteresis properties of Fe-based glass, proposed that cold deformation significantly enhances the attenuation and scattering of acoustic waves at low temperatures in metallic glass. Chen used positron annihilation technique to study the structure of the Pd-Cu-Si glass after cold rolling. It is proposed that the metal glass body after cold rolling does not have the same structure as the hole defect. To understand the metal glass body
