一、引言近年来很多作者利用內耗測量获得了不少关于形变后晶休內部結构变化的資料,这些研究的結果可以参看文献[1—7]以及它們所引的一系列文献。在这些研究工作中除了有一些是研究蠕变情况下內耗变化以外,絕大部分工作中形变是在室溫下进行的?蠹抑?在不同溫度下形变的晶体,它們結构会有很大的差别,这方面有很多作者用不同方法已获得大量的資料,但是問題仍然沒有彻底弄清还有待于进一步积累大量的資料。我們工作的目的是观察不同溫度下形变时內耗的变化,它們在保溫过程中的恢复以及不同溫度下形变晶体的內耗——溫度曲綫。从而来此較不同溫度下形变时結构变化的特点。
I. INTRODUCTION In recent years, many authors have obtained a lot of information about the internal structural changes of crystal grains after deformation through the use of internal friction measurements. The results of these studies can be found in References [1-7] and a series of references they cited. Except for some of these studies, which are studies of the change of internal friction under creep conditions, most of the work in the deformation is carried out at room temperature, Bend suppression? Crystal deformation at different temperatures, they will have a large structure There are many authors who have obtained a great deal of information in different ways. However, the problem still remains to be fully understood and a great deal of data needs to be accumulated. The purpose of our work is to observe the changes of internal friction during deformation under different temperatures, their recovery during the insulation process and the internal friction-temperature curve of the deformed crystals under different temperatures. Thus coming to this different temperature deformation of the structure characteristics.
