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. ...
Relationship Between Machinability, Microstructure, and Mechanical Properties of Al-7Si Alloy
(Amer Soc Testing Materials, 2018)
In this work, commercially available Al-7Si alloy was used, and the microstructure was modified by the additions of AlSr15, AlTi5B1, and Al3B. Cylindrical samples were cast into a sand mold and the machinability of the ...
The effects of degassing, grain refinement & Sr-addition on melt quality-hot tear sensitivity relationships in cast A380 aluminum alloy
(Pergamon-Elsevier Science Ltd, 2018)
Hot tearing tendency of A380 with various element additions (Sr, Sr + Ti, Ti, B and B + Sr) was investigated. Constrained rod casting (CRC) hot tearing test method was used to characterize the hot tearing sensitivity. ...
Development of High Purity, Few-Layer Graphene Synthesis by Electric Arc Discharge Technique
(Polish Acad Sciences Inst Physics, 2018)
In this study, high purity graphene nanoflakes (GNF) were synthesized by electric arc discharge technique. The arc discharge method is more advantageous than other graphene synthesis methods for producing cheap and ...
