B4C particulate-reinforced Al-8.5 wt% Si-3.5 wt% Cu matrix composites: Powder metallurgical fabrication, age hardening, and characterization
(Elsevier Sci Ltd, 2021)
The present work investigates microstructural and mechanical properties of B4C particulate-reinforced Al-8.5 wt % Si-3.5 wt% Cu matrix composites prepared by a successive process of mechanical alloying (MA), cold pressing, ...
In-situ synthesis of tungsten boride-carbide composite powders from WO3-B2O3-Mg-C quaternary system via a mechanochemical route
(Elsevier Sci Ltd, 2021)
In this study, in-situ synthesis of tungsten boride-carbide composite powders using a mechanochemical processing (MCP) method was investigated on the WO3-B2O3-Mg-C quaternary powder system. The raw blends of WO3-B2O3-Mg-C ...
Mechanochemical synthesis and consolidation of nanostructured cerium hexaboride
(Univ Novi Sad, Fac Technology, 2019)
This study reports on the mechanochemical synthesis (MCS) and consolidation of nanostructured CeB6 powders of high purity. CeB6 powders were prepared via MCS by milling CeO2, B2O3 and Mg powders in a high-energy ball mill ...
Change in Porosity of A356 by Holding Time and Its Effect on Mechanical Properties
(Springer, 2018)
In most of the practical casting operations, it is important to be able to cast large number of part with one single melt. Therefore, when quantity of the charge and melting crucible is increased, during casting process, ...
Experimental and statistical analysis of low velocity impact response of filament wound composite pipes
(Elsevier Sci Ltd, 2018)
Nowadays, filament wound composite pipes (GRP) are used as a structural element in many applications such as natural gas and oil transmission lines, and portable bridge constructions for military purposes. GRP pipes can ...
Effects of junction angle and gas pressure on polymer nanosphere preparation from microbubbles bursted in a combined microfluidic device with thin capillaries
(Elsevier Science Bv, 2018)
This study describes polymethylsilsesquioxane (PMSQ) nanospheres preparation from microbubble bursting in a 100 mu m capillaries embedded combined microfluidic device based on effects of junction angle and flow rate of ...
ON THE INTERPRETATION OF MELT QUALITY ASSESSMENT OF A356 ALUMINUM ALLOY BY THE REDUCED PRESSURE TEST: THE BIFILM INDEX AND ITS PHYSICAL MEANING
(Springer International Publishing Ag, 2018)
The oxide layer on liquid aluminum serves as a protective property to prevent the alloy from further oxidation. However, it has the potential to be a source of porosity when entrained into the bulk of the liquid. For this ...
Processing of layered porous mullite ceramics
(Springer, 2018)
In the current study, layered porous mullite ceramics with different pore sizes were produced via polymeric sponge method by using CC31 commercial-grade kaolin as starting raw material. Polyurethane sponges with three ...
EFFECT OF DEGASSING AND GRAIN REFINEMENT ON HOT TEARING TENDENCY IN Al8Si3Cu ALLOY
(Springer International Publishing Ag, 2018)
The effect of melt quality on hot tearing susceptibility of Al8Si3Cu alloy was examined under six different conditions, by using a traditional T-shaped mold. Grain refinement was carried out by two different modifiers: ...
Freezing Range, Melt Quality, and Hot Tearing in Al-Si Alloys
(Springer, 2018)
In this study, three different aluminum-silicon alloys (A356, A413, and A380) that have different solidification morphology and solidification ranges were examined with an aim to evaluate the hot tearing susceptibility. ...
