摘要：

Bulk specimenss for three point tests are produced from explosion clad austenite-ferrite material by electron beam welding bulk austenite and bulk ferrite to the respective surfaces. By milling, spark-erosion and fatigue cracks are introduced at and parallel to the interface in these specimens. At -30°C the crack extension force is the same for interfacial and bulk cracks in the ferrite. At room temperature the crack extension force for interfacial cracks is half of that for bulk ones, for suinterfacial cracks it lies between the two extremes. © 1990.
