Introduction . Titanium . is widely distributed throughout the whole universe such as . stars . and interstellar . Phase diagram: plot of pressure vs. Temperature summarizing all equilibria between phases.. Given a temperature and pressure, phase diagrams tell us which phase will exist.. Features of a phase diagram:. . Linda Green. Bay Area Circle for Teachers. 2012 Summer Workshop. Images from . virtualmathmuseum.org. Topics. What is topology?. Surfaces and gluing diagrams. The universe. A math auction. Most of this material is from . Alloys. Alloys are combinations or mixtures of elements.. Metals are alloyed to improve on properties of pure metals such as hardness, strength, corrosion resistance, etc. . Ex.:- Instead of pure aluminum an alloy of aluminum having combination of Al –Zn –Mg – Cu – Mn(A five element alloy ) is used to construct the air craft body.. GLY 4200 . Fall, 2016. 2. Binary Diagrams. Binary diagrams have two components. We therefore usually choose to plot both T (temperature) and X (composition) with pressure held constant. P-X (T fixed) or P-T (X fixed) are also possible. GLY 4200 . Fall, . 2017. 2. Unary Diagrams. Unary diagrams . have a single component. We therefore usually choose to plot both P (pressure) and T (temperature) since composition is not a variable. Examples. Given a temperature and pressure, phase diagrams tell us which phase will exist.. Features of a phase diagram:. Triple point: temperature and pressure at which all three phases are in equilibrium. . Vapor-pressure curve: generally as pressure increases, temperature increases.. Josef . Stráský. Lecture 3: Technological aspects of Ti alloys.
