Static and cyclic strength of bimetal prepared by surfacing method

The effect is studied of the magnitude of the operating repeated static load and the number of changes in heat conditions upon the development of diffusion bimetal interlayers (low-carbon unalloyed structural steel plus austenitic highalloy steel). When the material is heated at elevated temperatures under stress and when the temperature and stress change cyclically, the diffusion processes are accelerated. Then in the basic metal there appear decarbonization zones, whereas in the filler metal, carburization zones. The statical strenght is minium in the basic metal, the cyclical strength, in the diffusion zone metal
