Stress analysis of functionally graded disc under thermal and mechanical loads
(Elsevier Ltd, 2011)
In this study, the elastic stress analysis of annular discs made of functionally graded materials (FGMs) subjected to both uniform pressures on the inner surface and a linearly decreasing temperature distribution has been ...
Electrical conductivity and corrosion performances of in situ and ex situ AA7075 aluminum composites
(Polish Academy of Sciences, 2017)
The present study investigates corrosion behaviors and electric conductivity of AA7075 in situ (TiAl3) and ex situ (B4C) composites produced by powder metallurgy method. In production of in situ composites, various amounts ...
Corrosion behaviour and electrical conductivity of reinforced TiAl3 and B4C hybrid aluminium composites
(Polish Academy of Sciences, 2017)
In this study, corrosion and electric conductivity of aluminum hybrid composites (in situ TiAl3 and ex situ B4C) produced by powder metallurgy are investigated. Hybrid (in situ and ex situ) aluminum composite powders are ...
Effect of surfactant types on the size of tin oxide nanoparticles
(Polish Academy of Sciences, 2017)
In this study, tin oxide (SnO2) nanoparticles were synthesized by hydrothermal method in the presence of hydrazine and ammonia by adding surfactant for 12 h in a Teflon autoclave at 100°C reaction temperature. Tin(II) ...
Preparation and swelling properties of zeolite-poly(2-hydroxyethyl methacrylate-co-acrylic acid) hydrogel composites
(Polish Academy of Sciences, 2016)
