将四种工艺路线下的GH984G钢锭的4个试样用砂纸湿磨抛光后,通过SEM观察夹杂物的形貌,并结合EDS确定夹杂物的成分以及元素的分布。
After four samples of GH984G steel ingots under the four process routes were wet-ground and polished with sandpaper, the morphology of the inclusions was observed by SEM, and the composition and element distribution of the inclusions were determined with EDS.
