In-situ TEM Compression Pillar Test video for Fe-9%Cr ODS alloy and nanocrystalline Cu-24%Ta

<p>The first video for as-received Fe-9%Cr ODS alloy shows strain burst corresponding to load drops during deformation. The second video for 1 dpa, 500°C proton irradiated Cu-24%Ta alloy shows two-step grain boundary sliding corresponding to load drops at a triple junction. </p>原始态Fe-9%Cr氧化物弥散强化（Oxide Dispersion Strengthened, ODS）合金的第一段视频展示了变形过程中与载荷突降对应的应变突跳。经1每原子位移剂量（displacements per atom, dpa）、500℃质子辐照的Cu-24%Ta合金的第二段视频，则呈现了三叉晶界处与载荷突降对应的两步晶界滑移现象。
