【摘要】 铝基非晶合金的过热液体脆性参数M与弹性系数（杨氏模量E,剪切模量G和体积弹性模量K）之间的存在正的相关性,这是由于该种非晶合金是有着大的过热液体脆性参数M流动单元的非晶合金。此外,这些铝基非晶合金的K/G与T_g/T₁*（1/M）（Tg/T₁为约化玻璃转变温度）,过冷液体脆性参数m与玻璃形成能力（GFA）之间存在负的相关性。更多还原

【Abstract】 The positive correlations between the fragility parameter of superheated liquids,M,and elastic constants（Young’s modulus E,shear modulus G and bulk modulus K） were found in Al-based amorphous,which are attributed to the few flow units of an amorphous alloy with a large M Moreover,the negative relationships between the ratio,K/G and T_g/T₁ *（1/M）（T_g/T₁ is reduced glass transition temperature）,the fragility parameter of supercooled liquids,m,and the glass forming ability（GFA） are also found in these Al-based amorphous alloys.更多还原
