... Thermodynamics, and the Third Law of Thermodynamics. It informs that for transformations that occur at a constant temperature and pressure, the relative stability of the system is determined by its Gibbs free energy. The article describes the Gibbs free energy of a single-component unary system and the Gibbs...

.... Phase diagrams and the systems they describe are often classified based on the number of components (typically elements) in the system ( Table 1 ). A unary phase diagram plots the phase changes of one element as a function of temperature and pressure. A binary diagram plots the phase changes as a...

... compound such as iron and cementite; or several metals such as aluminum, magnesium, and manganese. These substances constitute the components comprising the system and should not be confused with the various phases found within the system. A system, however, also can consist of a single component, such...

..., it is helpful to understand the nature of the equilibrium relations among these phases. The relations are relatively simple for a one-component system, that is, a system consisting of a single, pure element. How is a metal put into the liquid condition for casting or into the vapor phase for...

... applications. Evaluating and comparing multiobjective optimization algorithms is more involved than evaluating and comparing single-objective algorithms. Rather than simply comparing the objective value at a single solution point and the number of system evaluations required to achieve the solution...

... slightly higher temperatures, between 550 and 585 °C (1020 and 1085 °F), but still below Ac 1 in the iron-nitrogen system for ferritic steels. Quenching is not required to produce the hard case but may be favorable in some cases. Because there is no phase transformation of the core material, nitriding...
