The effect of heat and strain during the semisolid processing route on microstructural evolution mechanical performance Al-5.5wt%Si-5wt%Zn-0.2wt%Mg alloy was evaluated. as cast heated partially melted to 588 °C (fs = 0.40), thixoformed (in an open die forged) solution heat-treated (SHT) at 525 for 1 6 h. chemical distribution (SEM-EDS) main alloying elements were evaluated each step route. SHT ...

The development of glass-ceramic foam has received significant attention in building and construction, given its potential for sustainability. This study investigated the low-temperature route fabricating foams from mining waste. feasibility one-step or chemical-aided sintering using granite powder, a naturally sourced waste, rather than already heat-treated wastes such as glass fly ash been ex...

A point in a transport network plays many roles. The Point pattern provides a flexible structure that decouples a point's role from the point itself and supports multiple concurrent roles. Points (or the links between points) are used to define routes. A route is a path through an ordered sequence of points (or links) in a transport network. A route may build upon different layers of components...

in this study, the adsorption of hexavalent chromium and zinc ions from the solution is investigated by raw red mud and mechanical-chemical activated red mud along with the possibility of selective reclamation of these ions from the solution. the mechanical-chemical activation of red mud was done by employing high-energy milling and subsequent acid treatment with hno3. raw red mud (rrm) and mec...

The present work deals with the synthesis and characterization of CdS nanoparticles with good thermal stability and optical properties by a novel and simple synthetic route. The nanoparticles were synthesized via chemical precipitation method in a single reaction vessel under ambient conditions. The prepared CdS nanoparticles were compared with the bulk CdS. The Optical properties were determin...

an improved chemical regeneration of the granular activated carbon (gac) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (caf) was investigated. in the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed gac is 103% of original gac. using oxidant and surfact...

chemical wastewater treatment is one of the attracting and common methods for wastewater treatment among the currently employed chemical unit processes. the use of coagulant-flocculant compound is one of the efficient methods for separating of paint and recovery of water. in this research, it was introduced and the effect of ph on removal of solid content from solution was studied experimentall...
