A separated flow model with stochastical trajectories has been developed to describe the fluidflow in a bubble stirred ladle.The bubble dispersion,turbulent cha
Using free bending method,the residual stress of the Ti(CN)coating on alloy Nb-752 wasmeasured to be 2-3 GPa of which the thermal stress cmounts to 10—20%.An a
The amorphous CoZr soft magnetic films with superior properties were prepared byradio-frequency sputtering under pressure of 0.5Pa Ar.The saturation magnetizati
Discussions were made of the principle,method and computer program for drawing the pre-dominance diagrams of the bi-metal co-existed system M<sub>1</sub>-M<sub>
A modified ion-plated TiN(IP-TiN) coating has been developed by adding 6 wt-% A1 andsmall amounts of La.Examination of this coating showed that the adhesion bet
The kinetics of the isothermal precipitation of(Nb,V)CN in Nb-V alloys has been investi-gated by using the Formastor-press simulator and the extraction replica
The intergranular cracking of 9% Ni cast steel seems mainly to relate to the segregation ofcontaminates H,S and P along boundaries.An addition of rare earth may
The solidification process of a horizontally continuously cast gray iron bar of 4.6cm in diame-ter was modelled.The function describing the distribution of heat
