is the thermal stability, which is defined by ΔT= Tf-Tg [14]. Another parameter introduced by HRUBY [15-16] is the glass forming ability (Kgl) which is defined as where Tf, Tg and Tl are the softing..., because they have a lot of advantages, such as low-softening point, low- dielectric constant and low thermal conductivity [2]. So, they can be useful in forming low-temperature, low- dielectric glass......
高Cu高强Zr基块体非晶合金的制备与力学性能 刘雄军1,张翠梅1,惠希东1,陈国良1 (1.北京科技大学,新金属材料国家重点实验室,北京,100083) 摘要:利用铜模铸造的方法制备了(Zr41.2Ti13.8Ni10Be22.5)1-x/87.5Cu12.5+x(x=1.6,6,11.2)块体非晶合金及其复相组织,分析了合金的相组成,热稳定性,力学性能及断口形貌.结果表明:随着铜含量的不断增多,尽管过冷液相区(ΔTx)逐渐增大,但非晶形成能力却不断下降.当合金的铜含量提高到18.5%时,非晶合金的压缩断裂强度达到2.2 Gpa,进一步增加铜含量到23.7%,压缩强度出现下降趋势. 关键词:Zf基块体非晶合金; 玻璃形成能力; 压缩断裂强度; Zr-based bulk metallic glasses; glass forming ability; compressive......
Effect of addition of Zn and Al elements on glass-forming ability and thermal stability of Mg-Cu-Y bulk metallic glasses LI Ye-sheng(黎业生), FU Qun-qiang(付群强), WU Zi-ping(吴子平), DONG Ding-qian... of these metallic glasses heated with a constant rate were calculated. The results show that Al element is greatly harmful to the glass-forming ability of Mg-Cu-Y alloys and cannot acquire bulk amorphous......
