Despite the continuous evolution on performance of refractory ceramic products, monolithic materials still require special attention during their processing steps as various phase transformations may take place curing, drying and firing stages. Drying is usually longest most critical process observed first heating cycle linings, enhanced particle packing reduced permeability resulting microstru...

Dimensional accuracy and geometric characteristics of the manufactured parts bear significant importance in product assembly. In Rapid Investment Casting, these can be affected by printing parameters Additive Manufacturing method used pattern production process. Stereolithography is one important AM techniques mostly exploited RIC due to its accuracy, smooth surface, precision. However, effect ...

Increasing demands for cement, iron and steel industries for refractories with suitable workability in severe conditions (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 ...

Conventional biodegradable polymers such as poly(lactic acid) (PLA) are an attractive alternative to replace traditional nondegradable food packaging films which plague the environment. However, PLA has shown not be degradable in some environmentally relevant conditions, including within freshwater systems. Additionally, suffers from very poor barrier properties, could result spoilage. Composit...

Additive manufacturing (AM) of metallic alloys for structural and functional applications has attracted significant interest in the last two decades as it brings a step change philosophy design manufacturing. The ability to fabricate complex geometries not amenable conventional manufacturing, potential reduce component weight without compromising performance, is particularly attractive aerospac...

Structural failure of concrete buildings on fire and complete destruction the monolithic refractory lining during their drying stage are dangerous examples effect explosive spalling partially saturated porous media. Several observations in both cases indicated presence moisture accumulation ahead front, which tune with most common theories concrete. Previous studies have shown evidence existenc...
