Abstract

Neutron stress diffractometry is used to study internal (residual) stress in a tape made of the AISI 310S stainless steel with a thickness of 100 μm and a width of 4 mm in three directions (along, across, and perpendicularly to the rolling plane). The residual macrostresses averaged over the tape length are determined at a segment of 40 cm. The macrostress distribution indicates a crescent-type deformation of the tape (bending in the rolling plane along the rolling direction). The correlation between macrostresses and internal microstresses is established (the stronger macrostresses, the higher concentration of the microstresses).

使用中子应力衍射分析第二代高温超导钢丝用AISI 310S不锈钢制成的带基材中的内部应力

摘要

中子应力衍射法用于研究AISI 310S不锈钢制成的带材的内部(残余)应力,该带材在三个方向(沿轧制平面,垂直于轧制平面和垂直于轧制平面)的厚度为100μm,宽度为4 mm。在胶带长度上平均的残余宏观应力在40 cm的部分确定。宏观应力分布表示带材的月牙形变形(在轧制平面中沿轧制方向弯曲)。建立了宏观应力与内部微观应力之间的相关性(宏观应力越强,微观应力的浓度越高)。
