All-weld-metal spectrometric chemical analyses were conducted on a cross section of each weld coupon. Nitrogen and oxygen determinations were made with LECO equipment extracting the samples from the broken ends of the tensile specimens.
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.

在每个全焊接金属材料的横断面进行光谱化学分析。利用LECO仪从拉长样本断掉的冷凝物中萃取样品,测定氮气和氧气的值。在顶部小珠处和Charpy V-凹槽处对横断面(2%尼特腐蚀)进行检测,这在前面已经描述过。500x下,在Charpy V-凹槽处对柱的区域片断和再加热部分进行测量。100x下,在样品顶部小珠处测量平均柱结晶颗粒宽度。为了在每次焊接中能够量化柱状结晶区的微观成分,需要用光显微镜在500x下,对顶部小珠100点数的10个区域进行测定。

所有焊接金属光计测定的化学分析进行了在各张焊接优惠券的一个横剖面。 氮气和氧气决心用LECO 设备被做了提取样品从拉伸标本的残破的末端。
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。

这么多,五分!
拿出点诚意来好不好
