Plates of A1-6Mg alloys with and without scandium were prepared by semi-continuous cast, homogenization,hot-rolled, cold-rolled and annealing. Based on studying
The method for preparing yttrium oxide with large specific surface area was introduced. By means of BET, SEM, TG and DTA analysis, the effects of precipitant, s
The optimum quenching rates and annealing conditions to prepare near stoichiometrical (Nd,Pr)12(FeCoZr)82B6 bonded magnets were investigated by using sub-overqu
The phenomena of acoustic emission in doped lithium niobate crystals were observed in the process of light-induced quasi-breakdown. It is found that the ultraso
The doping effect of rare earth elements (Tb and Sm) on the electronic structure of (110) martensitic twin boundary in Ni2MnGa alloys was investigated by using
