The effect of pressure on solidification structure formation in metal castings has been
reviewed and explicitly expressed by thermodynamic relationships. In particular, pressure …

Functionally graded materials, including their characterization, properties and production
methods are a new rapidly developing field of materials science. The aims of this review are …

The vast majority of rock masses is anisotropic due to factors such as layering, unequal in-
situ stresses, joint sets, and discontinuities. Meanwhile, given the frequently asymmetric …

The present study is to scale the inter-pore spacing and bubble radius required for
controlling the porosity of the lotus-type pores in the solid during a unidirectional …

Lotus-type porous aluminum with slender directional pores is fabricated via a continuous
casting technique in pressurized hydrogen or a mixed gas containing hydrogen and argon …

The stepped equivalent substitution approach has been applied to extend the Mori–Tanaka
model for predicting the elastic behavior of porous materials. A semi-infinite domain …

This paper explores the feasibility of laser joining of aluminum alloy 6111 panels with the
presence of lubricant used in the preceding stamping operation. The effects of two …

The dimensionless Niyama criterion was used to predict the formation of microporosity in
nickel-based superalloy casting, which extended the model application from a simple plate …

A special kind of microchannel heat sink is fabricated by a lotus-type porous copper in which
long cylindrical pores are arranged in one direction. By applying the straight fin model to the …

The effects of solidification rate on the shape of a pore, resulting from a bubble entrapped by
a solidification front, are investigated in this study. Solidification rate plays an important role …
