Conclusions
-
1.
After welding of steel 45 and R18 (without annealing) no noticeable redistribution of carbon occurs. After welding with subsequent annealing at 860°C for 6 h and 740°C for 4 h one observes substantial redistribution of carbon in the welded zone, steel 45 being decarburized and steel R18 carburized.
-
2.
Comparison of the diffusion coefficients calculated by the autoradiographic method with the data in the literature indicates that the autoradiographic method can be used to determine diffusion coefficients in a system of such complex composition. The variation of the microhardness in the welded zone matches the redistribution of carbon in this zone.
