Insight into ultra-refined grains of aluminum matrix composites via deformation-driven metallurgy
Composites Communications, 2021Abstract Ultra-refined grains were obtained in few-layer graphene nanoplatelets reinforced aluminum matrix composites via deformation-driven metallurgy under coupled thermo-mechanical effect. Fragmentation, thinning and re-dispersion of the reinforcements accelerated the nucleation of recrystallized grains and inhibited the migration of grain ...

Abstract This study investigated the effect of the microstructure refinement on the oxidation resistance of the Nb-6Mo-20Si-3Cr silicide-based alloy based on how the oxidation behavior of the alloy is severely affected by its microstructure size. Alloy powders were fabricated by a hydrogenation-dehydrogenation method, and were consolidated by a spark

Abstract The effect of calcium hexa boride (CaB6) on microstructure and mechanical properties of powder metallurgy CP-Ti and Ti-6Al-4 V was studied. CaB6 can scavenge the solid solution O during sintering, producing Ca-Ti-O and TiB second phases. These Ca-containing particles precipitate in the grain boundary to inhibit grain growth, resulting in the

Refining And Recycling Metallurgy In The Future
1992Abstract Refining metallurgy deals with the treatment of the extracted or recycled metal by purification and alloying. Traditionally, the refining metallurgist has had a good knowledge of extractive metallurgy and of the impurities present in the raw metal.

Abstract A small addition (≤0.5 wt%) of cerium silicide (CeSi 2 ) to powder metallurgy (PM) commercially pure Ti (CP-Ti), Ti–6Al–4V and Ti–10V–2Fe–3Al (all in wt%) results in substantial microstructural refinement and noticeably improved ductility with marginally improved sintered density. CeSi 2 is unstable and decomposes between 1423 K and 1473 K.

EKONOMIKA I UPRAVLENIE: PROBLEMY, RESHENIYA, 2022
In the context of the aggravation of the struggle for leadership between the United States and China, the introduction of anti-Russian sanctions, the task of assessing the potential for import substitution of refined petroleum products, mineral non-metallic products, metallurgy and metalworking products becomes especially urgent for Russia.
