The effects of heat treatment on microstructure and mechanical properties of the as-extruded Mg-9Sn-1.5Y-0.4Zr (wt%) alloy were investigated experimentally. The results show that the heat treatment plays an important role on the microstructure and mechanical properties of the as-extruded Mg-9Sn-1.5Y-0.4Zr alloy. The as-extruded alloy is mainly composed of non-uniform Mg2Sn phase. After the solution...
The effect of red mud, bone char and lime on the uptake and accumulation of lead (Pb), zinc (Zn) and arsenic (As) by maize planted in soil contaminated by heavy metals was studied. Five different treatments were designed: control, 5% red mud, 5% bone char, 5% lime, and 2.5% red mud + 2.5% bone char by weight. The maize was harvested 8 weeks after planting, and the concentrations of Pb, Zn, and As...
With the wide use of reverse osmosis technology in power plants, many produce water distribution networks of first-order reverse osmosis of seawater have severe corrosion, which is a threat for the normal and efficient operation of power plant. This paper studied the effect of corrosion factors such as dissolved oxygen, chloride ion, flow velocity, temperature on first-order reverse osmosis corrosion...
