DIAGRAM OF PHASE TRANSFORMATIONS IN THE AUSTENITE OF HARDENED ALLOY Fe - 28 percent Mn - 8.5 percent Al - 1 percent C - 1.25 percent Si AS A RESULT OF AGING DUE TO ISOTHERMAL HEATING

摘要

The phase composition and the morphology of structures formed as a result of isothermal holds in the range of aging temperatures of hardened alloy Fe - 28 percent Mn, 8.5 percent Al - 1 percent C - 1.25 percent S are studied. A diagram of the decomposition of initial austenite is plotted starting with the early stages and ending with the moment when the system attains the equilibrium state.
