Control of microstructure parameters that affecting the Al-Ti-C master alloys grain refining efficiency is leading to improve the aluminum grain refinement. This study was an attempt to produce Al-Ti-C master alloys that provide these controlling factors with relying on the solute effect theory. The produced master alloys were examined by using scanning electron microscopy (SEM), energy-dispers...

Abstract: Thermal fatigue is a stochastic process often showing considerable scatter even in controlled environments. Due to complexity of thermal fatigue, there is no a complete analytical solution for predicting the effect of this property on the life of various components, subjected to severe thermal fluctuations. Among these components, one can mention car cylinder, cylinder head and pi...

Abstract In this work, electron backscattered diffraction (EBSD) was used to examine the evolution of grain structure during friction stir welding aluminum alloy 6061-T6. entire FSW range studied, microstructure found be governed by continuous recrystallization. An increase in temperature resulted only microstructural coarsening.

Al2O3-ZrO2 ceramic coatings were prepared on 6061 Al alloy by Micro Arc Oxidation (MAO) and Selective Laser Melting (SLM). Coatings MAO exhibit a porous structure progressive oxidation of the substrate as function processing time. Those made SLM are denser, although presence cracks is observed throughout their surface. XRD results suggest that coating consists m-ZrO2, t-ZrO2 γ-Al2O3 phases for ...

Laser surface texturing is generally a promising approach to enhance the adhesion property of metal-thermoplastic hybrid structure, and effect related groove configuration. joining carbon fiber-reinforced thermoplastic (CFRTP) composite 6061 Al alloy under various configurations was carried out, aimed investigate width depth on interfacial morphology, mechanical properties, fracture behavior CF...
