Dr. Władysław Gąsior is a professor at the Institute of Metallurgy and Materials Science, Polish Academy of Sciences. He obtained his M.Sc. in 1976 from AGH-University of Science and Technology and his Ph.D. in 1994 from the Institute of Metallurgy and Materials Science, Polish Academy of Sciences. He is a member of the Polish Phase Diagram Committee, ASM International; a member of the National Committee for the Cooperation with the Associated Phase Diagram International Committee (APDIC); a member of the Associated Phase Diagram and Thermodynamics Committee, ASM International; a section member of the Theory of Metallurgical Processes of the Metallurgy Committee of the Polish Academy of Sciences; a member of the National Committee for the Cooperation with the Committee on Data for Science and Technology (CODATA); and a member of the Technical Sciences Commission of the Polish Academy of Arts and Sciences. His research topics mainly include activity measurements in alloys, measurements of the enthalpy of formation of intermetallic compounds, investigations of the surface tension, density, and viscosity of metals and alloys, modeling of the physical properties (surface tension and viscosity), wettability investigations of lead-free solder materials, and metallic materials for hydrogen safety storage.
