摘要
利用ＨＲＬ－１型热裂纹试验机，系统地研究了Ｃ，Ｙ，Ｃｏ，Ｍｏ，Ａｌ及Ｓｉ对纯镍型铸铁焊条热裂纹敏感性的影响。
The effects of C, Y,Co, Al, Mo and Si on the hot-cracking susceptibility of pure nickel electrode for gray cast iron welding are studied by using an HRL-1 type of hot-cracking test machine. The comprehensive utilization of C, Y and Co can remarkably improve the hot-cracking susceptibility of the pure nickel electrode for welding gray cast iron.
