Conclusions
-
1.
The degree of strengthening induced by combined treatment consisting of quenching and low-temperature tempering with subsequent plastic deformation is determined by the carbon concentration of the steel. The influence of alloyed elements is not mainfest, although we may note that silicon favors strengthening.
-
2.
The ductility after combined treatment depends on the concentration of alloyed elements.
Silicon, manganese, and chronium up to certain concentrations increase the ductility; the ductility decreases beyond this concentration. Nickel continuously increases the ductility at concentrations up to 5%. This phenomenon is apparently due to the influence of alloyed elements on the cold brittleness threshold.
