Modelling of retained austenite in carburized layers

Journal de Physique IV, 2004
In this paper, modelling of the phase composition of the carburized case produced on steel alloys containing chromium, manganese and nickel will be discussed. In particular, the effect of steel composition on the amount of retained austenite and carbide structure will be discussed.

Transformation of retained austenite in carburized 4320 steel

Metallurgical Transactions A, 1991
A systematic study of stress-induced and thermal-induced transformation of retained austenite in carburized 4320 steel with an initial retained austenite of 35 pct has been conducted. The transformation was monitored by recording the change in volume of smooth fatigue specimens.

Retained carbide distribution in intercritically austenitized 52100 steel

Metallurgical Transactions A, 1986
Two 52100 steels, one containing 0.009 pct P, the other 0.023 pct P, were homogenized at 1150 °C, slowly cooled to form proeutectoid carbides and pearlite, partially spheroidized, austenitized at 850 °C for one hour, oil quenched, and tempered at 200 °C.

Measurement of retained austenite using scanning electron metallography

Micron (1969), 1971
Abstract The volume percentage and distribution of retained austenite in two steels has been studied by scanning electron microscopy. Metallographically polished and etched samples were examined in the as-etched and replica-cleaned conditions. SEM results provide more information compared to other microscopic techniques because they take into account

Lattice parameter measurement in retained austenite by CBED

Proceedings, annual meeting, Electron Microscopy Society of America, 1983
The thin film (50-400 Å) retained austenite (ret-γ) (fig.1.a-b) has been identified at the lath boundaries of dislocated martensitic medium carbon (C) low alloy experimental steels, which were designed for structural applications. The existance of this parent γ-phase at the ambient temperatures has been attributed to several stabilization mechanisms in

Strain partitioning and mechanical stability of retained austenite

Scripta Materialia, 2010
The mechanical stability of austenite in steels which rely on transformation-induced plasticity is usually attributed to its chemical composition, size and shape. We demonstrate here that another factor, the partitioning of strain between phases with different mechanical properties, can dramatically influence the stability.
