Morozenko, B. Natapov] Conclusions: 1. In high speed steel copper dissolves in the matrix, it does not form strengthening phases and is not contained in the composition of the carbides. 2. Reliable changes of impact toughness or tensile strength at elevated temperatures of high speed steel under the effect of copper were not found. 3. In heating prior to hardening copper causes considerable coarsening of the austenite grain, and strength is reduced after hardening and tempering. 4. Within the investigated limits (0.15, 0.51, 1.4%) copper has practically no effect on secondary hardness, red hardness, thermal conductivity, thermal diffusivity, on the segregation and coagulation of the carbide phase in high speed steel, and it has a deleterious effect on the tool life.
