报告人研究方向:

  1) Preparation and study of physical and mechanical properties of metallic materials and alloys

  2) Study of hydrogen effect on metallic materials

  Biocompatible alloys based on Ti, Co, TiNi,

  Intermetallic alloys based on the Ni3Al, NiTi, TiNb and TiAl intermetallic compounds

  Ni superalloys

  Lightweight alloys for automotive industry

摘要:

  The mechanical properties of most engineering metallic materials are generally deteriorated by hydrogen presence. The brittleness of alloys induced by the hydrogen is observed at room temperature as well as at elevated temperatures. Nevertheless, in some cases the hydrogen can act as beneficial element in improving particular properties and moreover hydrogen is ubiquitous. The seminar will be focus on the following aspects:

  1. Detrimental influence in alloys of Ti, Ni, Al, steels

  2. Beneficial role in Ti alloys

  3. Hydrogen benefits in progressive materials
