• Resumen

  • Phase diagram calculations are an important topic in material science. They are usually carried out with limited-distribution software packages. This technology report is an introduction to software based phase diagram calculations. Three spreadsheets calculators are presented. The first one plots the Gibbs free energy versus composition for Al-Zn, Li-Mg, and Pelton's fictional A-B alloy. The second one calculates equilibrium phase composition for A-B. The third one calculates the Li-Mg temperature-composition diagram. The coding is reduced to a minimum and calculations are directly accessible to the user. The programs aim to be practice tools to complement instructor's lectures.
