Study of solid solution strengthening of alloying element with phase structure factors*

Using the empirical electron theory of solids and molecules (EET), the phase structure factors, n A and n B, of the carbon-containing structural units with mass fraction of carbon (ωC) below 0.8% and the mono-alloy structural units with ωC at 0.2% in austenite and martensite are calculated. The solid solution strengthening brought by C-containing interstitiall solid solution and alloy-substitutional solid solution in γ-Fe and α-Fe is discussed...
