Mg-9Li-5Al-1Zn-0.6RE alloy was prepared by vacuum induction heating. The microstructure and phases composition of the alloy were analyzed with optical microscop
In order to prevent BaMgAl10O17: Eu (BAM) phosphor from thermal degradation, MgF2-coatings on the surface of BAM were prepared by a sol-gel process. The coating
The kinetics on vacuum refining process of metallurgical grade silicon was studied using maximum evaporation rate,critical pressure and mean free path of phosph
<正>To understand the flow trace of semi-solid slurry in mold cavity, some thermocouples were inserted in mold cavity, and the reaction timing of thermocouples
The kinetics of internal oxidation of dilute Cu-Al alloys, containing 0. 447 5%-2. 214%Al (mole fraction) was investigated over the temperature range of 1 023 -
