- One universal in-situ deformation testing system has been installed successfully at the beamline BL12SW of Shanghai synchrotron radiation facility. The in-situ testing system was designed to apply multiple functions including tensile/compression and the simultaneously rotation along the tensile axis, as well as the electric heating of the metallic specimen. Two electrical torsional actuators enable the ω-rotation of the specimen along the tensile axis without blocking the beam by the columns of the loading frame. Lattice strain partitioning, texture evolution and imaging experiments have been conducted successfully.

- One self-designed testing system was utilized to investigate the creep behavior of the T92 steel in water vapour environment. The presence of water vapour accelerated the minimum creep rate and reduced the creep plasticity of T92 steel in the humid air. The hydrogen introduced by the formation of oxidation scale during the creep tests in water vapour environment presumably promoted the diffusion of Fe atoms with the reduced activation energy and then accelerated the creep rates in present research.
