Abstract

The new long duration experiment facility on beamline I11 at Diamond Light Source has been used to study the kinetics of sigma phase formation in three Cr-Co-Ni alloys. Diffraction data acquired during in situ exposure at 800°C for 50 d showed progressive increases in the sigma fraction. This was accompanied by changes in the proportions of the other phases, which differed markedly between the alloys studied. These results demonstrate the capabilities of the long duration facility for the study of metallurgical phenomena over periods of months to years, a capability not previously available at a synchrotron source.

摘要

金刚石光源I11光束线上的新型长周期实验装置已被用于研究三种Cr-Co-Ni合金中σ相形成的动力学。在800°C原位暴露50天期间采集的衍射数据显示，σ相分数逐渐增加。这伴随着其他相比例的变化，在所研究的合金之间有明显差异。这些结果证明了该长周期装置在数月至数年时间内研究冶金现象的能力，这是同步辐射源以前所没有的能力。
