The grain refining efficiencies of the master alloys are affected by many factors which include size, morphology of the grain refiner, melt holding time, melt

Basing on the results of MANOVA test it has been observed that the strongest significant effect on an increase of the tensile strength R m exerted the addition of Mg, followed by

The structure of the remelting zone of the steel C90 steel be- fore conventional tempering consitute cells, dendritic cells, sur- rounded with the cementite, inside of

Moreover, it was found that the recrystallized grain structure and relatively high martensite levels developed in the SZ lead to a significant drop in the mechanical properties of

The present work aims to improve the surface mechanical properties of the Ti-6Al-4V alloy by the combination of two plasma assisted processes: Plasma Nitriding and

The purpose of the present work is to improve the mechanical properties (elongation % and strength) of the hypereutectic Al-Si alloy using rapid solidiication, addition
