The effect of the tundish flux on evolution non-metallic inclusions in Si-killed 304 (18%Cr-8%Ni) stainless steel has been investigated at 1773 K. interfacial reaction between molten and CaO–Al2O3–MgO causes aluminum pick-up from liquid slag into melt, resulting a decrease oxygen content steel. originating modifies pre-existing Mn-silicate alumina-rich Because decreases as it reacts with flux, ...

increasing demands for cement, iron and steel industries for refractories with suitable workability in severeconditions (without any environmental risks), make the refractories’ researches to be an active area. refractories containing spinel has been developed with addition of chromia as a substitute in refractories using magnesite - chromite. in this research, different amounts of cr2o3 were a...

In this research, a new scheme of rapid prototyping using high-temperature castable materials for microfabrication of polymer lab-on-a-chip, which is used for micro-injection molding is proposed and characterized with extension of the replaceable mold disk technology. Showing perfect master mold creation of ultra-high density channel with aspect ratio of ~0.7, the proposed process is well fitte...

Satisfactory restoration in a patient with a partially edentulous situation can be challenging especially when unilateral or bilateral posterior segment of teeth is missing. Successful restoration can be done with various conventional and contemporary treatment options. One such treatment modality is attachment-retained cast partial dentures. This paper describes a case report of a patient with...

This study describes the role of in situ nano SiC whiskers on the strength and density of alumina silicate–SiC-carbonrefractory compounds. The prepared specimens were composed of 65 wt. % chamotte as alumina silicatecompound, 15 wt. % SiC-containing material regenerates and 10 wt. % fine coke and 10 wt. % liquid resole asbinder. Different values of additives (such as silicon a...

The binary tantalum–oxygen system is assessed using the CALculation of PHase Diagrams (CALPHAD) method with experimental data from literature. oxygen solubility in Ta solid-solution phase discussed and modeled. low- high-temperature modifications Ta2O5 are described as stoichiometric compounds. This dataset extended into ternary Al–Ta–O by complementing it datasets for Al–O Al–Ta literature add...
