采用XRD、SEM等技术分析了Mg_(61)Cu_(20.3)Ag_(8.7)Er_(10)合金的结构和断口形貌,研究了Mg_(61)Cu_(20.3)Ag_(8.7)Er_(10)非晶合金在不同温度和不同应变速率条件下的力学行为。结果表明,室温下非晶合金的断裂强度随应变速率的增加而降低。-100℃时,非晶合金不仅具有较高的强度,同时还表现出一定的塑性行为,此时,应变速率对于非晶合金的强度和塑性几乎没有影响。 |

The structures and fracture morphology of Mg_(61)Cu_(20.3)Ag_(8.7)Er_(10) amorphous alloy were analyzed using XRD and SEM.The mechanical behaviors of Mg_(61)Cu_(20.3)Ag_(8.7)Er_(10) amorphous alloy were investigated under different temperatures and strain rates.The results show that at room temperature,the fracture strength of the amorphous alloy is decreased with the increase of strain rate.When the temperature at-100 ℃,the amorphous alloy exhibits high strength as well as certain plasticity,The strain rates have little effects on the strength and plasticity of amorphous alloy. |
