Strength and ductility of chromium-manganese austenitic steel
Alloying of steel Kh10G14 with 0.26–3.01% Si has a negligible effect on the ductility after quenching from 1120°C, which ensures solution of the carbides in austenite. After quenching from 850°C the amount of M23C6, carbide increases with the concentrations of silicon and carbon; in this case the ductility decreases.
An increase of the carbon and silicon concentrations in the γ solid solution raises the yield strength in direct proportion. The increase of the yield strength due to the carbide particles is directly proportional to the cube root of the percentage of carbide.
