在650℃和750℃长期暴露条件下，用不同的透射电子显微镜观察了由共格伽马粒子强化的镍基高温合金的析出行为。扫描-透射式电子显微镜(STEM)的亮场图像。用常规的透射电子显微镜暗场图像和会聚束电子衍射(CBED)图对一次和二次共格γ‘析出物的颗粒尺寸分布、颗粒密度和体积分数进行了体视学评价。(C)2001 Elsevier Science Inc.保留所有权利。
The nickel-based superalloy Waspaloy, which is precipitation strengthened by coherent gamma' particles, was investigated using different transmission electron microscopy (TEM) imaging conditions in the as-received condition and after long time exposure at 650 degreesC and 750 degreesC. Scanning- transmission electron microscopy (STEM) bright-field images. conventional TEM dark-field images and convergent-beam electron diffraction (CBED) patterns have been taken for a stereological evaluation of the particle size distributions, particle density and volume fraction of primary and secondary coherent gamma' precipitates.
