This study reports on the mechanochemical synthesis (MCS) and consolidation of nanostructured CeB6 powders of high purity. CeB6 powders were prepared via MCS by milling CeO2, B2O3 and Mg powders in a high-energy ball mill ...

In most of the practical casting operations, it is important to be able to cast large number of part with one single melt. Therefore, when quantity of the charge and melting crucible is increased, during casting process, ...

In this work, commercially available Al-7Si alloy was used, and the microstructure was modified by the additions of AlSr15, AlTi5B1, and Al3B. Cylindrical samples were cast into a sand mold and the machinability of the ...

This study reports on the in-situ preparation of HfB2-HfO2 composite powders at room temperature by means of mechanochemical synthesis (MCS) from HfCl4-B2O3-Mg powder blends. The effects of milling duration and excess ...

Graphene nanoplatelets (GNP) were utilized as reinforcement for Al matrix with the aim of exploiting its extremely high mechanical properties. GNP reinforced composites were prepared via powder metallurgical processing ...

This work was carried out to evaluate the relationship between casting quality and wear properties of Al-12Si eutectic alloy with various Mg contents. Mg additions were selected as 0, 2, 3, and 4 wt.%. A permanent die ...

Aluminum matrix composites containing graphene nanoplatelets (GNPs) as reinforcement additive were fabricated by a two-step process consisting of mechanical alloying and pressureless sintering. The effects of graphene ...
