This study presents a study on the ductility performance of hybrid fibre reinforced concrete. The influence of fibre content on the ductility performance of hybrid fibre reinforced concrete specimens having different fibre volume fractions was investigated. The parameters of investigation included modulus of rupture, ultimate load, service load, ultimate and service load deflection, crack width...
Aluminum matrix composites reinforced with Al2O3 and SiC particles (5 Vol%) were produced using the hot powder extrusion method. Extrusion temperature and extrusion reduction in area were chosen in the range of 500 to 600°C and 90 to 95%, respectively. The physical and mechanical properties of the extruded composites such as density, tensile strength, elongation and microhardness were evaluated...

In this research, the production of Aluminum matrix composites (AMCS) consolidated by hot powder extrusion along with physical and mechanical properties of extruded bars have been studied. The matrix alloy was prepared from elemental powders of Al and 10wt% Ti. The composites comprises 5,10,15 or 20 vol% SiC or Al2O3 particles with an average size of 5 micron. The powder mixtures were sealed ...
The study tests the validity of tensile hot ductility test for assessing cracking during straightening operation. Steels with a thin film deformation induced ferrite (DIF) or fully auste...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
