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...

The application of additive manufacturing technology is one the main approaches to achieving rapid casting. Additive can directly prepare casting molds (cores) with no need patterns, and quickly cast complex castings. combination traditional break constraint technology, improve flexibility, ameliorate working environment. Besides, promotes realization “free casting”, greatly simplifying process...

Abstract Research on the behavior of bubble collision has always been one focuses in scientific field. This work kinematics and deformation bubbles when impacting curved boundary with hydrophilicity hydrophobicity. The impact process colliding wall was recorded by a high-speed camera. effects wettability radius curvature were analyzed. results show that collides hydrophilic wall, it will bounce...

The hydrostatic extrusion is a new method of extrusion process. The most important advantage of this method is reduction of friction and close tolerance for the coating thickness. In this study, the hydrostatic extrusion simulation of bimetallic wires has performed using of finite element method. In the following the advantages of hydrostatic extrusion compared to the direct extrusion are prese...

Abstract The corrosion and passivation behavior of the as-cast CoCrFeNiMo x ( = 0, 0.2, 0.4, 0.6, 0.8, 1.0) high entropy alloys (HEAs) are investigated. With addition Mo, increasing Mo Cr riched σ phase precipitates from primary FCC phase. resistance HEAs strongly depends on structure passive film. Generally, promotes selective dissolution enrichment 2 O 3 in film, former deteriorates while lat...

the current methods for treatment of cancers are inadequate and more specific methods such as gene therapy are in progress. among different vehicles, cationic liposomes are frequently used for delivery of genetic material. this investigation aims to prepare and optimize dotap cationic liposomes containing an antisense oligonuclotide (asodn) against protein kinase c alpha in non-small cells lung...

The use of industrial by-products of the vegetable oil industry as ductility increasing additives of polylactide (PLA) was investigated. Vegetable oil deodorization condensates were melt-blended by twin-screw extrusion up to a maximum inclusion quantity of 20 wt% without preliminary purification. Sample films were obtained by single screw cast extrusion. Compounded PLA films featured largely im...

It is becoming increasingly clear that the electronic properties of conjugated polymer films are strongly dependent on factors such as the conformation and the degree of aggregation of the polymer strands in the solution from which the film was cast. In this paper, we show how we can take advantage of conjugated ionomers ~conjugated polymers that have been functionalized with side groups that c...

In Sweden, high level radioactive waste will be disposed of in a canister with a copper outer and a cast iron or carbon steel inner. If the iron insert comes into contact with anoxic geological water, anaerobic corrosion leading to the generation of hydrogen will occur. This paper presents a study of the anaerobic corrosion of carbon steel and cast iron in artificial Swedish granitic groundwate...
