Abstract

The development and current state of instrumentation for the neutron diffraction study of internal stresses has been considered. During the last 15 years, significant progress has been achieved in the experimental techniques based on stationary and pulsed neutron sources. Specialized stress diffractometers have been developed, which make it possible to solve many engineering and technological problems, as well as problems of fundamental materials science. Two Russian neutron stress diffractometers are considered: FSD on the pulsed reactor IBR-2 at the Joint Institute for Nuclear Research and STRESS on the IR-8 reactor at the Natioanl Research Centre “Kurchatov Institute.” Examples of studies performed on these devices are presented.

材料和组件内部应力的中子研究

摘要

已经考虑了用于内应力中子衍射研究的仪器的发展和现状。在过去的15年中，基于固定和脉冲中子源的实验技术取得了重大进展。已经开发出专用的应力衍射仪，这使得解决许多工程和技术问题以及基础材料科学的问题成为可能。考虑了两个俄罗斯中子应力衍射仪：联合核研究所的脉冲反应堆IBR-2上的FSD和Natioanl研究中心“库尔恰托夫研究所”上的IR-8反应堆上的STRESS。展示了在这些设备上执行的研究示例。
