摘要
文献中极少能见到用穆斯堡尔效应研究TiNi合金的文章,这是因为TiNi合金中没有穆斯堡尔核素,而在其中产生穆斯堡尔发射源又是极其困难和复杂的工作。本工作在回旋加速器中用质子轰击Ti-51.6at.％Ni合金,获得了适合穆斯堡尔方法测量用的同位素。初步分析结果表明穆斯堡尔谱的参数对Ti_(44)Ni_(56)沉淀相是敏感的,并有助于了解TiNi合金微结构和性能。
The papers on using Mossbauer effect to study TiNi alloys were seldom seen in the past publications. It is because that TiNi alloys have no Mossbauer isotope and creating a man - made Mossbauer emitter in them is not easy. In this paper, a Ti - 51. 6at. % Ni alloy was bombarded by protons in a cyclotron and offered the isotope which is suitable to Mossbauer study. The preliminary results showed that Mossbauer parameters are sensitive to Ti44Ni56 precipitation and are helpful for understanding the change of microstructure and performance of the TiNi alloy.
