TTT diagram of isothermal transformations of a hypoeutectoid carbon steel; showing the main components obtained when cooling the steel and its relation with the Fe-C phase diagram of carbon steels. Austenite is slightly undercooled when quenched below Eutectoid temperature. When given more time, stable microconstituents can form: ferrite and ...
Frost diagram of various Ti alloys Microstructure of a part made from Titanium alloy TITANIUM-ALLOY CONSTITUTION Phase DIAGRAM - Alpha Peritectoid TITANIUM-ALLOY CONSTITUTION Phase DIAGRAM - Beta Eutectoid TITANIUM-ALLOY CONSTITUTION Phase DIAGRAM - Beta Isomorphous. Titanium alloys are generally classified into four main categories, [1] [2] [3 ...
22 Ti titanium (hexagonal) use: ... 74 W tungsten; use: 3695 K: 3422 °C: 6192 °F WEL: ... The bcc phase and the P-T and VT phase diagrams below 2 K".
The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas. The curves on the phase diagram show the points where the free energy (and other derived properties) becomes non-analytic: their derivatives with respect to the coordinates (temperature and ...

The unit cell of beta-tungsten. Beta-tungsten (β-W) is a metastable phase of tungsten widely observed in tungsten thin films.While the commonly existing stable alpha-tungsten (α-W) has a body-centered cubic structure, β-W adopts the topologically close-packed A15 structure containing eight atoms per unit cell, [1] [2] and it irreversibly transforms to the stable α phase through thermal ...
The solidus is the locus of temperatures (a curve on a phase diagram) below which a given substance is completely solid (crystallized). The solidus temperature specifies the temperature below which a material is completely solid, [ 2 ] and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium .
A binary phase diagram showing the most stable chemical compounds of titanium and nickel at different mixing ratios and temperatures. Phase transitions involving solutions and mixtures are more complicated than transitions involving a single compound.
