The calculated response was subsequently tested using the experimentally measured CCT data for a different AISI steel. As the characterization of continuous cooling kinetics requires knowledge of the phase diagram, a mathematical model based on thermodynamic equations is used to derive the phase diagram for this steel.
play a major role in the austenitic grain growth of 4140 steel. The first place to look to determine which temperatures to use can be found by using the phase diagram. The phase diagram shows at what temperature the material reaches its austenizing temperature. This

Hi, I'm doing heat treatments on a 4340 steel which is a nickel-chromium-molybdenum steel containing also manganese and carbon. Anyone knows which and how I can find the appropriate phase diagram for this low-alloy steel? thank you! RE 4340 phase diagram TVP ...
The Iron–Iron Carbide (Fe–Fe3C) Phase Diagram In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). The Fe-C phase diagram is a fairly complex one, but we will only consider the steel part of the diagram, up to around 7% Carbon.
Martensite is not shown in the equilibrium phase diagram of the iron-carbon system because it is not an equilibrium phase. Equilibrium phases form by slow cooling rates that allow sufficient time for diffusion, whereas martensite is usually formed by very high cooling rates.
Jun 19, 2018 · AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140.

In order to understand stainless steel, we need to know about the phase diagrams a little. And the base phase diagram in stainless steel is the iron-chromium binary phase diagram. In the phase diagram, you can understand that at specific temperature and chemical composition, we can predict the phases the alloy can contain.
4140 Annealed is fine quality alloy steel used for brake die tooling, support tooling, die holders, short run stamping and bending dies.
The Iron–Iron Carbide (Fe–Fe3C) Phase Diagram In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). The Fe-C phase diagram is a fairly complex one, but we will only consider the steel part of the diagram, up to around 7% Carbon.
AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition. Annealing. AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. Tempering. AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level.
Jul 09, 2002 · There is a huge difference between these two alloys chemically, namely the nickel content 4140 nominally has no Ni and 4340 contains between 1.65 and 2.00 % Ni. This contributes to substantial differences in hardenability and fracture toughness, and also has a positive effect on distortion during quenching and corrosion resistance.

form of iron, which is ignored here. Since all steels will pass through the single-phase austenite (γ, gamma) region and the heat treatment of steel is concerned with the conversion of γ to other phases at lower temperature, ignoring the δ-iron isn’t too serious. Four phases occur on the diagram in Fig. 1:
