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

Abstract The main objective of this paper was to perform sinterability studies of ball-milled Fe-12%Ni-6.4%Cu-1.6%Sn-0.6%C powders. A mixture of precisely weighed amounts of elemental iron, nickel and graphite, and pre-alloyed 80/20 bronze powders was ball-milled for 8, 30 and 120 hours. After cold-pressing at 400 MPa the specimens were sintered at 900oC for 30 minutes in a reducing atmosphere and subsequently tested for density and hardness as well as subjected to structural studies using scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis.

Hexagonal tungsten bronzes (h-MxWO3) are an emergent class of pseudocapacitive energy storage material: a metastable phase arranged in a hexagonal crystal structure that enhances the oxide’s rapid intercalation mechanism with impressive capacitances of over 200 F/g and excellent cyclability figures reported. 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.

Depending on the compacting pressure and sintering temperature, binary and complex phases are detected in the iron-bronze structure. The presence of solid lubricants in the composition of the composite material significantly reduces interaction of the liquid (bronze) and solid (iron) phases during sintering.

ABSTRACT One of the most important non-destructive methods for on-site analysis of bronze artifacts is portable X-ray fluorescence (XRF). However, bronze artifacts are usually heterogeneous in composition due to, among other things, the segregation of lead, which is hard to be eliminated through annealing treatments. In the present work, Cu-Sn-Pb alloys with homogenous composition and microstructure is fabricated by powder metallurgy technique. The suitability of the standard curve using Cu-Sn-Pb alloys by powder metallurgy as the standard samples for XRF on the analysis of bronze artifacts is

The evolution of internal structural damage under pressure was analyzed using XRD and SEM methods. The research results indicated that the optimal ratio of sodium sulfate, lime, and mineral powder is 1:1:0.

Streszczenie:

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
