Reasons for the chipping of the surface layer of a bimetal of high-manganese and carbon steels

1. The reason for the peeling of the working layer in bimetals of high-manganese steel + steel 08kp in tensile tests is the high concentration of phosphorus in the boundary zone. 2. Peeling of the working layer occurs in the zone with the largest quantity of phosphorus on the side of the base metal at a distance of 3–7 μm from the interface. 3. The phosphorus concentration in the zone of peeling amounts to 70–90% of its concentration in the working layer. 4. The addition of 0.85–1.6% Mo to high-manganese steel reduces localization of phosphorus in the boundary zone of the bimetal and eliminates peeling.
