【摘要】 用Ｘ射线衍射，拉伸试验，扫描电镜等方法研究了用真空单辊旋淬法制备的快速凝固Ｎｉ８０Ｐ２０非晶条带及其晶化处理后的纳米晶体的力学性能和拉伸断口形貌。结果表明，非晶态Ｎｉ８０Ｐ２０和纳米晶Ｎｉ８０Ｐ２０都具有很好的力学性能，其拉伸断裂强度分别为１１７０ＭＰａ和１２７０ＭＰａ，且弯折１８０°不断。更多还原

【Abstract】 The mechanical properties and photographys of facture surfaces for amorphous Ni-P alloy and nanocrystalline Ni-P alloy was investigated by means of X-ray diffra-cion,tensile test and SEM, The ribbon of amorphous of Ni80P20,prepared by single rollermelt spinning technique under vaccum,to form nanocrystalline alloys.The amorphous Ni-Palloy and nanocrystalline alloy have good mechanical properties。The tensile fracturestrength is 1170 MPa and 1270 MPa respectively。Alloy can be bent 180 degrees withoutfracturing。更多还原
