Slip activity in dwell fatigued Ti-6Al-2Sn-4Zr-2Mo, and its relation to the microstructure, was investigated using digital image correlation and electron backscatter diffraction at room temperature, 120 °C, and 200 °C to span a range of dwell sensitivities. The grains through which slip traces traversed were examined to identify critical grain characteristics in the percolation of long-range slip. It was found that slip accumulated more rapidly and in greater amounts at temperatures that exhibit dwell sensitivity (room temperature and 120 °C) versus temperatures that do not (200 °C). At all temperatures, plasticity occurred primarily by long-range basal slip through co-located grains with a high basal Schmid factor.

在室温，120°C和200°C下使用数字图像相关性和电子背散射衍射研究了停留疲劳的Ti-6Al-2Sn-4Zr-2Mo的滑动活性及其与微观结构的关系，以涵盖一定的停留范围敏感性。检查了滑移痕迹所穿过的晶粒，以确定在远距离滑移渗流中的关键晶粒特征。已发现，在表现出驻留敏感性（室温和120°C）的温度下，滑移积累得更快，而在没有停留温度的温度下（200°C）积累的滑移量更大。在所有温度下，可塑性主要是通过具有较高基础施密特因子的同位晶粒的长距离基底滑移而发生的。
