Fiber metal laminate (FML) is a kind of lightweight material that has garnered much attention in recent years due to its excellent properties under tensile, flexure, and impact conditions. However, little been paid the evolution aluminum alloy during FML forming process. In this paper, effects specimen thickness non-isothermal process on creep behavior AA2024 alloy, which generally used FMLs, w...

in this study, the isothermal reduction of iron oxide pellets, made of iranian chadormalo, gole-gohar, and sangan iron ores, was investigated in the temperature range of 900-1100°c. tabas, pabdana, babnizoo, karmozd, and shahrood domestic coals were used as reductants. parametric studies were performed and the effects of such factors as temperature, average particle size of iron ore and coal fi...

Isothermal solidification process of pure metal Al was studied by molecular dynamics (MD) simulation using EAM potential. The effects different cooling rates on the isothermal metallic were studied. first subjected to a rapid process, and then it annealing under conditions. mean first-passage times (MFPT) method Johnson-Mehl-Avrami (JMA) law used qualify kinetic processing, nucleation rate, cri...

Dendritic growth experiments were conducted in the reduced-convection environment aboard the space shuttle Columbia on STS-87. Spectral analysis was performed on 30-frame/s video data during growths of isothermal dendrites. Results indicate that pivalic acid dendrites exhibit a subtle oscillatory behavior of the axial growth velocity near the tip, with a frequency component that is associated w...

A Monte Carlo algorithm to simulate the isothermal recrystallization process of snow is presented. The snow metamorphism is approximated by two mass redistribution processes: surface diffusion and sublimation-deposition. The algorithm is justified and its parametrization is determined. The simulation results are compared to experimental data, in particular, the temporal evolution of the specifi...

To improve the interfacial stability at high temperatures, n-type skutterudite (SKD) thermoelectric joints with sandwich structures of Ti/Mo/Yb0.3Co4Sb12 were successfully designed and fabricated. In this structure, Mo and Ti were introduced as the barrier layer with the goal of suppressing the interfacial diffusion and the buffer layer with the goal of enhancing the bonding strength, respectiv...

the kinetics of molybdenite oxidation was studied by non-isothermal tga-dta with heating rate 5 ºc.min-1.the model-fitting kinetic approach applied to tga data .the coats-redfern method used for model fitting. the popular model-fitting gives excellent fit for non-isothermal data in chemically controlled regime. the apparent activation energy was determined to be about 34.2 kcalmol-1 with pre-ex...
