摘要: 本文报道了Ni-P非晶在不同退火温度下磷的表面偏析和脆化行为及二者之间的关系。发现近表面区在退火过程中形成一个贫磷层,其厚度随温度增加,磷的贫化程度随退火温度加剧。本文从非晶中原子扩散激活能可变化的观点出发,对弛豫过程中元素再分布和脆化机制进行了讨论。
关键词 Ni-P非晶元素再分布退火脆性    
Abstract:The surface segregation of P and the embrittlement, also their rela-tions, of Ni-P amorphous annealed at temperatures below crystallization have beeninvestigated. A P-depleted layer was found nearby the surface during annealing.The P-depleted layer became thicken and the depletion of P became severe as theincrease of annealing temperature. The mechanism of elementary redistrib utionand annealing embrittlement during relaxation Was discussed on the viewpoint ofthe activation energy of atomic diffusion in Ni-P amorphous being variables.
Key wordsNi-P amorphous    element redistribution    annealing embrittlement
