Resistance spot welding (RSW) includes many variables that can influence the weld properties. The purpose of this study is to develop an analytical model for prediction of thermal history and weld microstructure in RSW and to find the most important process parameters that influence the weld microstructure. A one dimensional model is proposed for prediction about thermal history during cooling ...
Ammonium Perchlorate (AP) is one of the most important oxidizer in composite solid propellants. Therefore, synthesis and application of nanoparticles as catalyst for improving thermal decomposition of AP is an important issue in catalysis research. There are a great many nanomaterials for the thermal decomposition of AP such as nano metal particles, metal oxides, metals salts, metallic composit...
In this research, CuO spherical-like nanoparticles were synthesized using the planetary ball mill method. The structure, particle size and morphology of the resulting CuO nanoparticles were characterized by XRD (X-ray diffraction), SEM (scanning electron microscopy) and SAXS (small-angle X-ray scattering) methods. The results of this investigation showed ...
Ammonium perchlorate (AP) is considered as a strong oxidizer in solid propellants. Therefore, its thermal decomposition characteristics directly influence the combustion behavior of solid propellants. The AP particle size, shape, and morphology influence on the thermal behavior. In this study, the solvent anti-solvent crystallization method equipped with an eductor mixer was used as a system fo...
The thermal stability of Al1-xInxN (0≤x≤1) layers was investigated by scanning transmission electron microscopy (STEM) imaging, electron diffraction, and monochromated valence electron energy loss spectroscopy during in-situ annealing from 750 C to 950 C. The results show two distinct decomposition paths for the Inrichest layers (Al0.28In0.72N and Al0.41In0.59N) that independently lead to trans...
The high-temperature (HT) phase of Y(BH(4))(3) has been prepared by heating of the as mechanochemically synthesised low-temperature (LT) phase of Y(BH(4))(3) to 194-216 °C and subsequent rapid cooling to ambient temperature. Although the differences in the crystal structure and vibrational spectra for these closely-related polymorphs are rather small, yet the NMR MAS (1)H and CP MAS (89)Y spect...
