The Open Limit Point Compactness

In this paper, we gave a new topological concept and we called it the open limit point compactness.We have proved that each of the compactness, and the limit point compactness is stronger than of the open limit point compactness., that is, compactness implies open limit point compactness, also limit point compactness implies open limit point compac

Reclamation of intermetallic titanium aluminide aero-engine components using directed energy deposition technology

Titanium Aluminide (TiAl) alloys are intermetallics that offer low density, high melting point, good oxidation and corrosion resistance compared to Ni-based superalloys.As a result, these alloys are used in aero-engine parts such as turbine blades, fuel injectors, radial diffusers, divergent flaps, and more.During operation, aero-engine components
