| 摘 要： | 在自制的ZL－1型超强度脉冲电流发生装置上，对35钢的电磁势效应理裂纹止裂效果进行了初步研究。结果表明：利用电磁热效应可在放电瞬间在裂纹尖端形成焊口，使裂纹尖端曲率半径增大，达到抑制裂纹扩展的目的。对裂纹尖端热影响区的显微组织进行了分析。

| Abstract: | Using theory of electromagnetic heat effect,the possibility of crack arrest on 35 steel was studied by super intention pulses electric current generator.The results show that a small welded joint can be formed at crack top due to the result of heat concentration effect,when pulse electrical current was applied.This result can be used to crack arrest.At same time,the microstructure at the front top of the crack was analyzed too. |
