The item deals with the possibilities of utilization HVOF coatings in thermal cyclic loading conditions. There were evaluated three types of coatings based on WC-Co, WC-Co-Cr and Cr3C2-25NiCr. The quality of coatings was evaluated in terms of their adhesion as sprayed and also during the cyclic thermal loading, EDX analysis and evaluation of microhardness. Construction and structure of coatings...

Tensile tests were carlied out on con~mercialty available NiTi alloys in order to study their mechamcal d~aracterirtics up to tlie onsct of thc superelasticity effect. Two realtimc supporting techniques, adiabatic thermal emission and acoustic emission, were employed. Thermal ekssion allowed to follow local temperature variations in the material due to loading, while acoustic emission was able ...

Pursuant to the high usage of rotating the disk in aircraft gas turbine engine, turbo pumps in oil and gas industries, steam and gas turbines in power plants, marine gas turbine and other industrial rotary machines designing and getting under the mechanical and thermal loading casued this design and analysis to be as a special significance. These disks are subjected to mechanical and thermal lo...

Submitted for the MAR14 Meeting of The American Physical Society Atomistic study of rejuvenation of amorphous metals via thermal loading MASATO WAKEDA, Osaka University, JUNJI SAIDA, Tohoku University, JU LI, Massachusetts Institute of Technology, SHIGENOBU OGATA, Osaka University — Rejuvenation is the structural excitation of amorphous system accompanied by enthalpy and free volume rise, and i...

in this article, thermal stability of beams made of functionally graded material (fgm) is considered. the derivations of equations are based on the one-dimensional theory of elasticity. the material properties vary continuously through the thickness direction. tanigawa's model for the variation of poisson's ratio, the modulus of shear stress, and the coefcient of thermal expansion is...

This study investigates the effects of calcium carbonate (CaCO(3)) nanoparticles on the mechanical and thermal properties and surface morphology of polycaprolactone (PCL)/chitosan nanocomposites. The nanocomposites of PCL/chitosan/CaCO(3) were prepared using a melt blending technique. Transmission electron microscopy (TEM) results indicate the average size of nanoparticles to be approximately 6...
