283abstractO2 不同试验温度下夏比冲击试验摆锤刀刃对于冲击吸收功的影响李和平 周星 徐惟诚 王红鑫(宝钢分公司 制造治理部,上海 202541)摘要:夏比冲击试验机的摆锤刀刃有 2mm 和 8mm 两种曲率半径,本文介绍了在冲击吸取功和温度关系图的上平台区、下平台区和脆性转变区两种刀刃关于冲击吸取功的阻碍。关键词:夏比冲击试验;下平台区;脆性转变区;上平台区Effects of the Striking Edge Radius of the Charpy Impact Test on the Absorbed Energy at Different TemperatureLI Heping, ZHOU Xing, XU Weicheng, WANG Hongxin(Manufacturing Management Department, Baosteel Branch, Shanghai 202541, China)Abstract: There are two different types of strikers with 2mm and 8mm in radius. Different effects of the striking edge radius on the Charpy impact test in lower shelf zone, transition zone and upper shelf zone of absorbed energy and temperature curve are described in this paper.Key words: Charpy impact test, lower shelf zone, transition zone, upper shelf zone
