During sintering of Wbronze metal matrix composites, the difference in the interdiffusuion path, sintering atmosphere and alloying element might be the source of the swelling phenomenon. In this study, the factors lead to swelling of Wbronze sintered compacts were investigated. To achieve this goal, two swelled groupes of Wbronze sintered compacts were examined. The first group was compacts of ball milled powder with activator additions and the second group was compacts of ball milled powder infiltrated by bronze melt. The latter type showed the severest level of swelling. Sintered density mea

A symmetrical pseudocapacitive device composed of h-MxWO3 electrodes negates the need for expensive and problematic rare minerals such as cobalt and lithium instead using low-cost tungsten whilst offering more efficient high-rate energy storage than commercial lithium-ion batteries.

ABSTRACT One of the most important non-destructive methods for on-site analysis of bronze artifacts is portable X-ray fluorescence (XRF).

In the present work, Cu-Sn-Pb alloys with homogenous composition and microstructure is fabricated by powder metallurgy technique.

Abstract:
Abstract Natural fibers have gained relevance because its a positive environmental impact, primarily due to their often being derived from waste and their production processes being less polluting compared to synthetic fibers. Coconut husk is a residue that enables the production of these fibers; however, for every ton of fiber produced, two tons of particulates are obtained. In this context, the objective of this study is to develop anticorrosive piping coatings by incorporating coconut husk particulates. The size of the residue was characterized through laser particle size analysis. X-Ray Di
