The aim of this study was to investigate the potential application metal foams in shell-tube recuperators. A356 aluminium foam cast around internal and external surfaces a thin-walled copper tube enhance heat transfer between separated water streams at different temperatures. results demonstrated that drastically increased efficiency due its large volumetric surface area high thermal conductivi...

The flow stress and dynamic recrystallization behavior of A356 aluminum alloy was studied, with a strain rate ranging from 0.001 s?1 to 1 temperature 300 500 °C. Both the true stress–strain curves microstructure examination indicated that occurred during isothermal compression. A physical model based on Arrhenius equation developed, this can accurately predict fraction Finally, implemented in F...

The hot-deformation behavior of A356 aluminum alloy with a Sr modification was investigated using Gleeble 1500 thermal simulator. true stress-strain curves deformation temperature 300–500 °C and strain rate 0.01–5 s–1 were clarified. activation energy the 221.474 kJ/mol. influences friction on investigated, then constitutive equation established. results show that flow stress is obviously affec...

In this study, A356T6 wheel bending fatigue test limits determined using the finite element methods and compared to experimental results. test, zinc-glycerin was applied front surfaces of wheels obtain detects. Short long cycle tests (200.000 1.800.000 respectively) were performed. Simulation model created in Ansys by defining A356 S-N curve. performed has been with parameters. According simula...
