This current study reports preparation of Nickel-Gadolinium doped Ceria (Ni-GDC) composite via controlled unidirectional freeze casting of aqueous-based GDC slurry completed with nickel infiltrated into the porous GDC samples. Gadolinium doped ceria powder prepared by gel-combustion synthesis method. The oxide powder was confirmed to be the fluorite-structured of Ce0.8Gd0.2O1.9 solid solution b...

Abstract Multi-axial compression of the mushy zone occurs in various pressurized casting processes. Here, we present a drained triaxial apparatus for semi-solid alloys that allow liquid to be drawn into or expelled from sample response isotropic compression. The rig is used measure pressure-dependent flow stress and volumetric during isothermal globular Al-15 wt pct Cu at 70 85 vol solid. Analy...

1 ABSTRACT The continuous casting process is a widely used technique in modern steel plants. However, it is a complicated process that is not well understood. The objective of this research is to model the porosity and macrosegregation due to shrinkage related effects and solid deformation in the continuous casting of steel. Solid phase movements due to bulging and variable roll gap are modeled...

Semi-solid metal (SSM) processing has been an attractive method for manufacturing near-net-shape components with high integrity due to its distinct advantages over conventional forming technologies. SSM employs a mixture of solid phase and liquid slurries and/or non-dendritic feedstocks as starting materials shaping. Since the original development from 1970s, number processes have developed sha...

In this paper, we obtain a generalized version of the wellknown distance function family Lp norm. We prove that the new functions satisfy distance function properties. By using these functions, convex symmetric shapes can be described as loci, the set of points which are in equal distance from a given point. We also show that these symmetric convex shapes can be easily parameterized. We also sh...
