A vacuum brazing process using BNi7+3% Cu composite solders to braze Cr18-Ni8 steel was carried out. The joint can be divided into three zones: Isothermally Solidified Zone (ISZ), Athermally Solidified Zone (ASZ) and Diffusion Affected Zone (DAZ). The characteristics of microstructure were observed by scanning electron microscope (SEM). The element distribution in the Cr18-Ni8 steel brazed joint and...
A novel cubic Zn 0.7 Mg 0.3 O film on silicon substrate is conducted by KrF excimer pulsed-laser ablation system. By introducing a thin TiN buffer, layer-by-layer growth of cubic Zn 0.7 Mg 0.3 O film epilayer has been realized. The overall growth process was monitored in situ by reflection high-energy electron diffraction (RHEED) method. It was found that the crystallinity...
