Optimization of Powder Preheating and Process Parameters on Hardness and Porosity of Al–CNT–Mg Composites through Powder Metallurgy Using the Taguchi–ANOVA Method

Aluminum-based nanocomposites are promising lightweight materials for engineering applications due to their high specific strength. Powder metallurgy combined with Taguchi L27 experimental design and ANOVA was used to evaluate the effects of the powder thermal preconditioning temperature, mixing time, and compaction pr...

Identification of the performance characteristics of a propeller pump as a propeller turbine in response to variations in rotational speed

Innovations continue to be developed in the field of new and renewable energy, particularly in hydropower, namely the use of pumps as turbines to replace conventional turbines in decentralized energy systems for areas not yet connected to the central power grid, in order to meet basic needs. The object of this study is...
