Current Interested Fields 1. Irradiation damage of nuclear materials: The goal of this research is to study on irradiation damages in pure Fe, low Cu model steels and China’s domestic A5083 RPV steels using positron annihilation spectroscopy, a powerful tool to detect vacancy-type defects and defect’s chemical environment, combining with SEM, TEM, APT and nanoindentation measurements.
2. Corrosion and irradiation of metals and alloys using positron annihilation spectroscopy: (a) corrosion and irradiation of Zircaloys; (b) corrosion-related defects and enrichment of copper in aluminium and aluminium alloys; (b) corrosion and protection of AM60B magnesium alloy;
3. Application of positron annihilation techniques as new methods of non-destructive testing for the various materials: Our goal is to develop new non-destructive testing (NDT) methods using positron annihilation spectroscopy. This system can be developed for use both in the laboratory and in the field. Proprietary methods identify damage in metal alloys prior to crack formation. This enables a highly sensitive means for many practical NDT applications of metal alloy condition such as cold working, heat treatment, operational damage, and manufacturing process effects, including differentiating the microstructure variations associated with phase changes.
