Interfacial Microstructure Formation in Al7SiMg/Cu Compound Castings

Modelling of Equiaxed Microstructure in Castings

The paper deals with a numerical modelling of equiaxed microstructure formation during the solidification of two-component alloys. The basic enthalpy formulation was applied to model the solidification. The equiaxed grain size was dependent on the average cooling velocity at the moment when the liquid metal reaches the liquidus temperature. The experimentally determined dependence between grain...

Microstructure and physical properties of alloys for partial denture castings.

Changes in the properties of cobalt-base alloys have been investigated from many points of view,1-4 but basic reasons for these changes have not been considered in any depth. Many variables are involved, and the relationships between the variables are closely interconnected. Some of the variables that have been studied are casting technicsj4 amounts of elements present,5'6 and investments used....

Al-7Si-Mg Semi-Solid Castings – Microstructure and Mechanical Properties

Interfacial Microstructure of Chromium Oxide Coatings

Chromium oxide coatings are chemically inert, have high mechanical strength, hardness and good optical characteristics; therefore, they have been widely used in many applications including corrosion protection, wear resistance, electronics, and optics. Cr2O3 is well suited for wear resistance applications, as it is one of the hardest oxides with 29.5 GPa hardness. Several deposition techniques ...
