Al_2O_3/SiO_2 ceramic core nano-composites were prepared and their microstructure was investigated by transmission electron microscope(TEM). The results show th
Through morphology observation on silicon particles of Al-Si-Cu-Mg cast alloy, it is found that during solution treatment the evolution of eutectic silicon morp
The phenomenon, characteristics and influence factors of dechromisation of a Cu-Cr alloy in acid solutions containing Cl~- were studied by means of metallograph
