Abstract A stable capillary liquid jet formed by an electric field is important physical phenomenon for formation of controllable small droplets, power generation and chemical reactions, printing patterning, chemical-biological investigations. In electrohydrodynamics, the well-known Taylor cone-jet has a stability margin within certain range flow rate ( Q ) applied voltage V ). Here, we introduce simple mechanism to greatly extend produce very high throughput. For ethanol emitting from...
The mechanical properties and microstructure of aluminum matrix composites containing zircon (10, 15 20 wt.%) as a reinforcement particles cobalt additive (1, 1.5 2 were investigated. prepared by powder metallurgy technique sintered in both conventional microwave furnaces at temperatures higher than the melting point aluminum. results revealed that density strength increased introducing particles. maximum was obtained adding 10 wt.% furnace 950ºC. phase analysis scanning electron microscopy...
In this paper, Al2O3–SiC composites were produced by SPS at temperatures of 1600 °C for 10 min under vacuum atmosphere. For preparing samples, Al2O3 with the second phase including micro and nano-sized SiC powder milled 5 h. The powders sintered in a machine. After sintering process, studies, densification mechanical properties examined. Results showed that specimens containing micro-sized have an important effect on bulk density, hardness strength. highest relative strength 99.7%, 324.6 HV...
Fusion welding of nickel-based superalloys with a total Al and Ti content more than 6% has always been challenging. The reason for this is the occurrence solidification liquation cracks during welding. Investigating mechanisms formation these two types can increase theoretical practical insight necessary to achieve welded alloy without cracks. objective research was look at link between liquidation fractures in Nd:YAG pulsed-laser GTD-111 nickel-base superalloy joints. choosing method...
In this research, the feasibility of adding mechanically activated nano-crystalline Al2O3 particles into aluminum matrix was investigated. For purpose, powder milled in a high-energy ball mill for 20 h. Subsequently, 1 wt.% added to molten Al. Then microstructure, characterizations and mechanical wear properties composite were studied. Peak broadening diffraction patterns clearly showed that crystallites nanometer scale after milling. Furthermore, distributing small amount on heterogeneous...
