Conclusions
-
1.
The first stage of martensite decomposition is two-phase in rhenium steels with 0.3–1.4% C and 10–20% Re, and three-phase in steels with 1.6–1.7% C and 3–6% Re.
-
2.
Increasing the carbon and rhenium concentrations of the steel lowers the rate of the first stage of decomposition.
-
3.
With increasing concentrations of carbon in the steel the tetragonality of the ϰ martensite lattice increases, as a result of the larger elastic deformation of the lattice resulting from coherence with the lattice of precipitates rich in carbon.
