Rational control of the structure and properties of manganese steels of type 20GL using hardenability parameter. Part 3. Rational control of the structure of toughened steels of type 20GL

The possibilities and methods of rational control of the structure and properties of steels of type 20GL subjected to hardening and tempering are considered. The main methods of the study comprise control of the chemical composition of the steel (including a study in terms of the hardenability parameter), of the modes of heat treatment of the castings, and of some additional metallurgical and technological effects (modifying and microalloying).

Rational control of the structure and properties of manganese steels of type 20GL using hardenability parameter. Part 2. Rational control of the structure and properties of normalized steels of type 20GL

The possibilities and methods for rational control of the structure of steels of type 20GL for substantial enhancement of the properties to meet the requirements of the strictest national standards and performance specifications of advanced producers are considered. The methods discussed involve control of the chemical composition of the steel (including that according to the hardenability parameter), of the modes of heat treatment (normalizing) of castings (mutually coordinated with respect to the equivalent cooling rates), and of some additional metallurgical and process operations (modifying, microalloying, thermocycling, etc.).

Influence of alloy elements on the properties of manganese steels in the 293?4�K temperature range

1. With an increase in manganese and carbon contents in austenitic Fe-C-Mn steels their mechanical properties at temperatures of 293 to 4°K increase and the magnetic permeability decreases. 2. Alloying of Fe-C-Mn steels with chromium leads to a significant reduction in their magnetic permeability, but sharp embrittlement at cryogenic temperatures occurs. 3. Aluminum has a favorable influence on the mechanical properties of Fe-C-Mn steels but leads to an increase in their magnetic permeability. 4. The combined addition to the steels of chromium and aluminum makes it possible to obtain in them a satisfactory combination of mechanical and magnetic properties which makes the Fe-C-Mn-Cr-Al system promising in the development of low-magnetism materials for cryogenic purposes.

Use of the method of experiment planning to investigate the mechanical properties of manganese steels

1. Composition-property diagrams obtained in using the simplex-lattice method of experiment planning for manganese steels on varying the elements within the range from 6.0 to 8.0% of Mn and 0.05–0.60% of C make it possible to optimize steel compositions with respect to mechanical properties.

Effect of vanadium on the structure and properties of high-manganese steels

Vanadium has a substantial effect on the structure and properties of manganese steels. It leads to an increase in the quantity of carbides and greatly increases the effect of dispersion hardening of austenite. Aging is particularly effective for steels with a high concentration of manganese (10–13%) and vanadium (>4%).

Niobium in carburized manganese steel

1. Niobium (0.06–0.16%) has a favorable effect on the mechanical properties of manganese steel, resulting in high strength with satisfactory ductility. 2. Small niobium additions prevent the formation of a cementite network in the case, reduce the amount of retained austenite in the case, retain a sufficient amount of carbon in solid solution, and increase the toughness and wear resistance of the carburized steel. 3. Carburized steel 15G2B can be used for critical machine parts.
