Importance of Mathematical Modeling (Response Surface Methodology) in Equal Channel Angular Pressing
Abstract: Severe plastic deformation is a technique for producing a deformation. Equal channel angular pressing is one of the unique methods for producing high plastic deformation in Aluminum alloys due to its quality of having the same dimensions after processing. In present work, A die was designed on the basis of a mathematical model generated by RSM. Variation in die geometry and other conditions were represented in present work. ANOVA presented …

Synthesis, Spectral characterization and biocidal activities of Triphenyl antimony (V) halide and methoxide complexes
Abstract: The schiff base ligands N-mono(salicyclidene)-σ-phenylenediamine (spdH) and N-mono(2-hydroxy-1-naphthalidene)-σ-phenylenediamine (hnpdH) and their triorganoantimony (V) complexes were synthesized by conventional method, were characterized by UV, IR and 1H NMR spectral studies which proposed that in the complexes of the ligands spdH and hnpdH, antimony is seven coordinated and in sp3d3 hybridization state with pentagonal bipyramidal geometry. Keywords: halide, methoxide complexes, triphenylantimony (V)

A Traffic Analysis and Redesign of Transportation Facilities: A Case of Imam Abdullah Bin Saud Road and Khaled Bin Al Walid Street Interchange
Abstract: According to the definition of transportation, a movement of people and goods from one location to another location, we look for transportation facilities to contribute to a smooth traffic movement in a desirable and sustainable manner. Therefore, in case there is any facility which is suffering from chronic congestions, then it is inevitable to consider an improvement of it. The intersection which is located at Imam Abdullah Bin Saud Road …

Predictive Model to Monitor the Effect of Angular Momentum of an Electron in an Orbital
Abstract: Mathematical model was developed to examine the effect of angular momentum of an electron in an Orbital. The Lamor procession and vector of angular momentum function of the S,P orbitals revealed increase in the angular momentum with increase in orbital. The trend on spd orbital in terms of angular momentum shows the same behaviors as well as spdf orbital. The quantum angular momentum shows that the energy of the system …

Advancements and Innovations in Superalloy CoatingTechniques: A Comprehensive Review of ECAP andHigh-Temperature Aluminization
Abstract: Equal Channel Angular Pressing (ECAP) is a pivotal technique within Severe Plastic Deformation (SPD), widely recognized for its exceptional capability to refine grain structures in metals and alloys down to the micro- and nanometer scales. This review offers an in-depth examination of the ECAP process, highlighting its effectiveness in generating ultra-fine grain microstructures that significantly enhance the mechanical properties of materials, such as strength, hardness, and ductility. We provide a …
