Phase Equilibria and Phase Diagrams (Phase Equilibria of Materials) 재료 상평형 (Fall Semester, 2013)

Intro

phase equilibria  thermodynamics equil thermo: materials take on and the in which states would ideally be assumed thermo: kinetics, rate of evolution toward equil one of the important subfields of thermo  theory of since this course is theoretical, best to begin with a brief outline of what a physical theory is physical theory: attempting to understand and predict by modeling it replaces the world: useful ↔ useless (O) right ↔ wrong (X)

→ common underlying structure theory → common underlying structure ① 정의 (definitions or vocabulary) ② 가정 (assumptions or postulates): laws, axioms, assumptions ③ 수학 (math): mathematical consequences of postulates, used to explain and predict the detailed behavior of the model ④ intuitive extrapolations: the final step of a theory, interpreting and explaining the behavior of systems outside the strict range of the model → a familiar example is classical ‘ ’

heat, a quantity defined by laws of thermo, not a thing thermo → science of heat, a quantity defined by laws of thermo, not a thing (classical) thermo thermo laws 0th: defining empirical temp, eq. of state 1st: internal energy, eq. of state 2nd: entropy, absolute temp, eq. of state 3rd: entropy complement
