Effect of rapid quenching on the electrochemical properties of AB5 and AB3.5-type hydrogen storage alloys was studied. The results indicated that the discharge
Minor addition of Sc to aluminum results in the rapid precipitation of homogeneously distributed Al3Sc dispersoids. The presence of Al3Sc dispersoids is more ef
The purpose of this project is to control the pollution of dust, which occurred in a typical lead-zinc mine. Two kinds of surfactants and water glass were chose
The kinetics of pressure leaching high iron sphalerite concentrate was studied. The effects of agitation rate, temperature, oxygen partial pressure, initial aci
Heavy duty engine valve head was prepared by Ni76Cr19AlTi alloy. It was coated by cobalt-base alloy on the surface to promote its wear-resistance. Hardness test
