| 摘 要： | 利用真空单辊旋淬法制备了一系列Al-La—Y—Ni(Fe)四元合金的快速凝固条带,研究了它们形成非晶的能力、条带的力学性能以及拉伸断口形貌结果表明:当合金成分为85—90at-%Al(La+Y)<10at-%时,能获得既具有高强度、高韧性又具有较好热稳定性的Al基非晶合金。其最高拉伸断裂强度和显微硬度分别为760MPa和294DPN,且弯折180°不断,Al与La—Y间的强相互作用及合金的低熔点(T_m)是促使Al-La—Y—Ni(Fe)合金形成非晶相的主要因素

| Abstract: | The ribbons of amorphous Al-La-Y-Ni (Fe) quarternary alloys, prepared bysingle-roller melt spinning technique under vacuum, superior strength, ductility and thermalstability may be achieved when the alloy contains 85-90 at.-% Al and less than10at.-% La+Y. The maximum tensile fracture strength and microhardness are as high as 760MPa and 294 DPN, respectively. As-quenched ribbons can be bent 180 deg without frac-turing. The dominant factors for formation of amorphous Al-La-Y-Ni (Fe) are the strongattractive interaction among Al, La, Y and a low melting temperature. |
