Abstract
Bimetallic specimens were prapered through explosion clad 1Cr18Ni9Ti/20G and in order to measuring their mechanical properties the electron beam welding of bulk 1Cr18Ni9Ti and bulk 20G on the both respective sides was carried out. Cracks were introduced at the interface in the specimens by milling and spark-erosion. Both the resistance curves loaded by symmetric three-point bending and fatigue crack growth behaviors loaded by symmetric four-point bending were investigated for the bi-materials interface and the bulk materials. The results showed that the resistance to crack growth along the bi-material interface was always less than those of respective counterpart materials for both static and dynamic loadings.
