CaSnO3 with the perovskite structure was prepared by wet-chemical route and the electrochemical properties as anode material for lithium ion batteries were stud
Through morphology observation on silicon particles of A1-Si-Cu-Mg cast alloy, it is found that during solution treatment the evolution of eutectic silicon morp
The friction sheets working process was analyzed. It is found that its characteristic is microregion instantaneous high temperature and the current cooling meth
The brazing of Al2O3 to Nb was achieved by the method of transient liquid phase (TLP) bonding. Ti foil and Ni-5V alloy foil were used as interlayers for the bon
The isothermal sections of Ni-Cr-Nb ternary system at 1 323 K and 1 423 K were determined by means of diffusion triple and energy spectrum analysis (ESA). By an
To improve the penetrating ability and the welding quality of keyhole plasma arc welding, a novel penetration closed-loop control system was established. In the
