Abstract

The structure and tensile properties of diffusion bonding of hard magnetic alloy 25H15K with low carbon steel 3 processed by pressure welding in vacuum using interlayer of nickel. The microstructure of the compounds was investigated by scanning electron microscopy, electron microprobe analysis of the data presented, as well as microhardness measurements. It was shown that the yield stress of the bonding is about 540 MPa. Failure occurs on the joining zone of hard magnetic alloy with a nickel interlayer.
