摘要

金属在强脉冲离子束辐照及其后的快速冷却过程中所经历的应力过程是强脉冲离子束金属材料改性的最重要的机制之一。对应于这种过程

金属材料的微观结构和微硬度发生了改变。本文以45#钢和纯铝为样品

将实验中测量到的不同强度的强脉冲辐照后样品微硬度和微观结构的变化与热力学计算所描述的热力学过程相对照

解释了出现微硬度双峰是由于应力波的形成和传播使然

并预言了由于应力波的在样品背面的反射

在较强能通量的强脉冲离子束辐照下样品背表面一定深度处也会出现微硬度增加的现象

该现象已被实验所证实。

Abstract

The stress process samples undergo during the intense pulse ion beam (IPIB) irradiation and sequent fast cooling is one of the most important effects of IPIB. It can change the microstructure and microhardness of the samples. By comparing thermodynamic calculation with the experimental results of microhardness measurements for 45# steel samples and pure Al samples which are irradiated by IPIB at different energy fluence

we suppose that the generation

propagation and reflection of stress wave should account for the phenomenon of multi-maximum of microhardness. The experimental results also proved our deduction about the microhardness maximum appearing at a certain depth near the back side surface.
