A recently developed technique of surface alloying by diffusion-coating has been used to produce coatings on Mg alloys with various Al and Zn contents. The experimental results show that both Al and Zn solutes in the alloy promote the diffusion of al

Several studies have confirmed the applicability of the inverse growth restriction theory for predicting grain size in titanium alloy systems. However, until now, no work has identified nuclei particles that could be used to refine the β-grain size

Trace additions of boron to commercial purity titanium result in significant microstructural changes. Changes include the promotion of dendritic growth and refinement in both the prior-β and α-grain size. Boron partitions strongly on solidification

High pressure die casting is the most important production method for casting magnesium alloy components, and uniformity of appearance is an important criterion for acceptance of a component by customers. This paper investigates the influence of unif

The boundary element method (BEM) was used to study galvanic corrosion using linear and logarithmic boundary conditions. The linear boundary condition was implemented by using the linear approach and the piecewise linear approach. The logarithmic bou

Soldering reactions are commonly observed during high pressure die casting of aluminium alloys, and involve the formation and growth of interfacial intermetallics between the die and the cast alloy. It is generally believed that close to 1% Fe is nec
