摘要

本文叙述一个用

轰击镍和不锈钢样品产生辐射损伤的实验。

由回旋加速器产生，能量为72.5MeV，辐照程度在0.15~0.5dpa之间。辐照效应用三种方法进行测量分析：透射电子显微镜观察、形变热激活分析和正电子湮没技术。观测结果表明：经过辐照以后在镍中产生了空洞，而在不锈纲中损伤不明显。

Abstract

In this paper

the experiment of radiation damage of nickel and stainless steel by

C-ions bombardment is described.

C-ions are accelerated to 72.5MeV by 1.5m cyclotron. Irradiation dose of each sample is in the range of 0.15~0.5 dpa. The radiation effects have been studied by means of three methods: Microstructure of the sample after irradiation has been observed with transmission electron microscope. The activation volume has been measured by means of tensile test. The results of three methods show that voids occur in nickel sample but the radiation damage of stainless steel is not obvious.
