<正>Nb-15W-18Si-xHf(x = 0, 5,10 and 15, mole fraction, %) alloys were prepared by arc melting and then homogenized at 1 750℃for 50 h. The microstructure and me
Compared with a conventional Hall-Heroult cell(H-H cell), the interpolar distance of a drained cell can be reduced significantly and the cell voltage and heat p
A numerical model was developed to describe the coarsening of the second phase droplets under the common action of nucleation, diffusional growth and Brownian c
During the solidification of Bi-Mn alloys from the mushy zone between 262℃ and 355℃ in a static magnetic field up to 1.0T,the alignment behavior of the MnBi p
The principle of thermal flux being constant in heat-flow-tube and the principle of heat balance were applied to analyze and calculate the steady-state thermal
