- Abstract
- The high-cycle fatigue (HCF) behavior of dissimilar metal welds between high-Mn (HM) steel and 304L stainless steel was investigated at 298K and 110K. The resistance to HCF of the 25Mn/304L weld joint was comparable to that of a 304L/304L weld, even at 110K. The HCF behavior of the dissimilar metal joints between HM steel and 304L could be reasonably predicted by the ultimate tensile strength at both room and cryogenic temperatures, as with the base metal. The failure locations and micro-hardness studies suggested that both geometrical and metallurgical factors were important in determining the HCF behavior of 25Mn/304L weld joints.
