Abstract:

The criterion-base iterative stepwise Backward Elimination (BE) method was used to predict Au according to the main variables (Ag, Cu, Pb, and Zn). The optimization process of the quadratic polynomial model are carried out on different trenches. Whereas, Pb and Zn with Ag×Zn and Pb×Zn are significant to determine the lateral dispersion of Au. It means... More

Abstract:

Hot cracking susceptibility of fillers 52 and 82 in 800H and 825 nickel-base superalloys was discussed using the Spot Varestraint test. The fillers of 52 and 82 were added into nickel-base superalloys via a gas tungsten arc welding (GTAW).Experimental results showed that the hot cracking sensitivity of the nickel-base superalloys with filler at high temperature...

Abstract:

Graphene is a two-dimensional hexagonal monoatomic layer crystal composed of carbon atoms, which exhibits the shape of a honeycomb and plays an important role in the fields of optics and mechanics. It also has the advantages of high specific surface area, strong chemical stability and special planar structure. It is an ideal carrier for carrying various... More

Abstract:

High temperature applications such as turbine blades for aeronautics or molten glass-shaping tools require the use of refractory metallic materials. Among the later ones, cast superalloys based on some transition metals and reinforced by MC carbides stay in good place and their metallurgy merits to be well known. This work consists in a general exploration... More

Abstract:

In this study, the usage wastewater from secondary treatment in feeding fishes of Carassius gibelio species and suitability of the fishes for human food were evaluated. The metals (Ag, Al, As and B) in treated effluent and skeleton, skin, eyes and brain tissues of fishes were examined seasonally. It was found that treated effluent was... More
