Conclusions
-
1.
The yield of austenitic high-manganese steels can be raised by 100–250 N/mm2 as a result of disperse-carbide segregation when they are alloyed with tungsten.
-
2.
Steels with 15–20% Mn, 10% W, and more than 0.65% of C possess the best combination of mechanical properties in the initial and quenched states.
-
3.
Cold plastic deformation makes it possible to increase the yield point to 1500–1600 N/mm2 with satisfactory plasticity.
