One possible microstructure of Ti-6Al-4V alloy with equiaxed alpha grains and discontinuous beta phase. Ti-6Al-4V titanium alloy commonly exists in alpha, with hcp crystal structure, (SG : P63/mmc) and beta, with bcc crystal structure, (SG : Im-3m) phases. While mechanical properties are a function of the heat treatment condition of the alloy ...
Si*Sé is a downtempo and electronic group from New York City.The main members of the band are Carol C (vocals, DJ) and Cliff Cristofaro (producer). Other members of the band include Ryan Farley (drums), Neil Ochoa (percussion) and Morgan Phillips (Bass).
Titanium aluminide has three major intermetallic compounds: gamma titanium aluminide (gamma TiAl, γ-TiAl), alpha 2-Ti 3 Al and TiAl 3. Among the three, gamma TiAl ...
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 ...
CALPHAD stands for Computer Coupling of Phase Diagrams and Thermochemistry, a methodology introduced in 1970 by Larry Kaufman, originally known as CALculation of PHAse Diagrams. [1] [2] [3] An equilibrium phase diagram is usually a diagram with axes for temperature and composition of a chemical system. It shows the regions where substances or ...
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.
The phase diagram with phosphorus shows SiP and SiP 2. [88] A reported silicon phosphide is Si 12 P 5 (no practical applications), [89] [90] formed by annealing an amorphous Si-P alloy. The arsenic–silicon phase diagram measured at 40 Bar has two phases: SiAs and SiAs 2. [91]
Phase diagram of the GeSbTe ternary alloy system. GeSbTe is a ternary compound of germanium, antimony, and tellurium, with composition GeTe-Sb 2 Te 3.In the GeSbTe system, there is a pseudo-line as shown upon which most of the alloys lie.
