AN OVERVIEW OF THE INTERACTIONS BETWEEN REINFORCEMENTS AND AL MATRICES WITH SI, CU AND MG AS ALLOYING ELEMENTS IN ALUMINUM MATRIX COMPOSITES: CASE OF OXIDE REINFORCEMENTS

Abstract Oxides (Al2O3, SiO2, TiO2, ZrO2, Y2O3, CeO2, MgO) are among the most used reinforcements for Aluminum Matrix Composites (AMC); while the combination of Al with Si, Cu and/or Mg excels among the alloying systems used as matrices.Some works in literature study the effects of the reinforcements and the alloying elements on the composites manu

The article analyzes the main methods and principles of the organization of Nazi agitation and propaganda during the Weimar Republic.The relevance of this problem is preconditioned by modern socio-political processes associated with the ideological brainwashing of the electorate during the election campaign to obtain its support in the elections.In

This paper proposes an improved evolutionary algorithm with parallel evaluation strategy (EAPES) for solving constrained multi-objective optimization problems (CMOPs) efficiently.EAPES stores feasible solutions and infeasible solution separately in different populations, and evaluates infeasible solutions in an unusual manner, such that not only fe

The type-I interferon (IFN) system represents the first line of defense against viral pathogens.Recognition of the virus initiates complex signaling pathways that result in the transcriptional induction of IFNs, which are then secreted.Secreted IFNs stimulate nearby cells and result in the production of numerous proinflammatory cytokines and antivi

Grain boundary solute segregation is becoming increasingly common as a means of stabilizing nanocrystalline alloys.Thermodynamic models for grain boundary segregation have recently revealed the need for spectral information, i.e., the full distribution of environments available at the grain boundary during segregation, laguna 3hp dust collector in
