Transmission Electron Microscopy Sample Preparation of INCONEL 738 Nickel-Base Superalloy
Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...
متن کاملPreparation and Characterization of Diols and Polyols Based on Aminolysisof Poly (ethylene terephthalate) Wastes with Alkanolamines
The Plastic Waste phenomenon, which is the result of increasing poly (ethylene terephthalate) production and the wide range PET consumption in different industries, caused one of the major environmental concerns. Therefore,many different ways have been studied and applied for chemical recycling of PET. One of the most important ways to depolymerize poly (ethylene terephthalate) is the aminolysi...
متن کاملPreparation and Characterization of High Specific Surface Area γ-Alumina Nanoparticles Via Sol-Gel Method
In the present investigation, γ-alumina nanoparticles with particle sizes less than 10 nm, high specific surface area (351 m2/g), high pore volumes and relatively narrow pore sizes distribution was prepared via sol-gel method in presence of aluminum isopropoxide as an aluminum precursor, distilled water, acetic acid as hydrolysis rate controller and tert-butanol as solvent. They had meso ...
متن کاملPreparation and Characterization of SiO2-CaCl2 Nanocomposite by the Sol-Gel Method
The SiO2-CaCl2 hybrid porous materials were prepared by the sol-gel method. This process was conducted by the hydrolysis and condensation of Tetraethyl orthosilicate (TEOS) by replacement of ethanol from alcogel and drying at the ambient temperature to obtain xerogel structure. The alcogel samples were synthesized from TEOS, EtOH, H2O, HCl, NH4OH and CaCl2, while the total molar ratio of the co...
متن کاملPreparation and Characterization of Nanostructure Akermanite Powder by Mechanical Activation Method
Objective(s): So far, extensive research has been conducted on the preparation and characterization of nano ceramics based on Ca-Si by sol- gel method and bioactivity was evaluated, but, a few researches have paid attention to the preparation of materials by mechanical activation (MA). The aim of this study was the preparation of akermanite nano powder by mechanical activ...
متن کاملElectrochemical Preparation and Characterization of Mn5O8 Nanostructures
Electrochemical synthesis followed by heat-treatment is a facile and easy method for preparation of nanostructured metal oxides. Herein we report nanostructured Mn5O8 prepared through pulse cathodic deposition followed by heat-treatment for the first time. For the preparation of Mn5O8 nanorods, pulse cathodic electrodeposition was first done from 0.005M Mn(NO3)2 at the current density of 5 mA c...
