Examination of cress sections (etched with 2% Nital) was carried out in the top beads and in the Charpy V-notch location (),as described previously().the area fractions of columnar and reheated zones were measured at 500x at the Charpy V-notch location. The average width of the columnar grain size (prior austenite grains )was measured in the top bead of the samples, at 100x. To quantify the microstructural constituents of the columnar zones, in each weld , 10fields of 100 points were measured, in the top bead, at 500x by light microscopy.
水芹部分的考试(被铭刻与2% Nital) 被执行了在顶面小珠和在Charpy V-notch 地点(),如所描述previously() 。柱状和被重新加热的区域的区域分数被测量了在500x 在Charpy V-notch 地点。 柱状粒度的平均宽度(预先的austenite 五谷)was 测量了在样品的顶面小珠, 在100x 。 定量柱状区域的微结构组成部分, 在各焊接里, 100 点10fields 被测量了, 在顶面小珠, 在500x 由光学显微学。
