摘要
本文描述单试样直流电位法监测低合金高强锅炉压力容器钢板 BHW35三点弯曲试样裂纹启裂点和启裂韧度δ_i(COD)。还提出带 CHARPY-V 型侧槽试样监测高韧度材料启裂韧度的有效途径。
This paper presented here shows that DIRECT-CURRENT ELECTRICAL POTENTIAL DROP (DCPD)can be used to determine crack initiation and initiation toughness value δ_i of low alloy high strength steel plate BHW35 which is generally used to manufacture boiler drums and pressure vessels by three-point bend speci- men and other high toughness materials by CHARPY-V type side-grooved specimen.
