Grain refinement is of importance for metallic materials since it provides multiple benefits, such as improved castability, reduced casting defects and mechanical properties. From extensive research carried out in the past decades, has been widely accepted that solute one crucial factors achieving grain refinement. However, a complex phenomenon, depending on not only solutes melt to provide gro...

The fatigue strength of high silicon-alloyed nodular cast iron is influenced by casting defects and graphite precipitates. literature as well the findings this work show that these microstructural constituents can be tailored controlling silicon microsegregation. In addition, segregations also affect ferritic matrix microstructure locally. present work, in ductile are specifically manipulated s...

In recent years, magnesium-based alloys and composites have great attention in automobile, structural, biomedical industries due to their desirable characteristics such as lower density, low elastic modulus, high specific strength, better damping properties, excellent castability. The pure magnesium was used a matrix material reinforced with fly ash fillers of different compositions weight perc...

The production of clean steel involves the controlling, elimination, or modification of nonmetallic inclusions. In Al-killed steels, alumina is the main type of inclusion. Calcium treatment, by wire feeding, is commonly used to modify solid alumina inclusions to calcium aluminates, which exists in a fully or partially liquid phase. Liquid inclusions can improve steel castability, but make inclu...

Magnesium alloys have gained considerable interest as a material for automotive and aerospace applications due to its low density, high specific strength, and good castability. However, another considerable issue is their corrosion properties. This restricts their practical applications. In this present research, corrosion behavior of the AZ31B magnesium alloy was evaluated by conducting salt f...
