one of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. in this paper, the authors have studied thermal behaviour for schiff base ligand and their synthesized cobalt, nickel complexes. in this method, the sample is opposed to a controlled temperature change and its physical properties. here we studied melting point and tg...

application of supramolecular polymer blending in preparation of materialswith adjustable mechanical properties is addressed. it is anticipated that the microstructure and properties of polymer blends are drastically controlled by the inter-molecular interactions. on this basis, the effect of strongly dimerising ureidopyrimidinone end groups (upy) with the capability of quadruple hydrogen bondi...

Ionomers are generally described by copolymers having either acrylic or methacylic acid as one component and the other component is mostly either ethylene or styrene. The objective of this research was to study the thermal behaviour and stability of ionomers of styrene with some alkali metal acrylates. These materials have been synthesized by neutralization of the respective copoly...

An experimental investigation was conducted to find the effect of spraying method of coating of Thermal Barrier Coatings (TBCs) on their oxidation behaviour and resistance to various thermal loading. Isothermal and thermal shock tests were performed in order to study oxidation behaviour of air plasma sprayed Bond Coat (BC) and assess its effect on TBCs lifetime under the stated loadings. Specim...

This artcile is concerned with thermal buckling and thermal induced free vibration analyses of PCPs (perforated composite plates) with simply supported edges applying a mathematical model. The stiffness and density of PCP are defined locally using Heaviside distribution functions. The governing equations are derived based on CLPT. The present solution gives reasonable results in comparison with...

The thermal expansion behaviour of silicon carbide (SCS-2) fibre reinforced 6061 aluminium matrix composite subjected to the influenced thermal mechanical cycling (TMC) process were investigated. The thermal stress has important effect on the longitudinal thermal expansion coefficient of the composites. The present paper used experimental data of the thermal expansion behaviour of a SiC/Al comp...
