Microstructure and irradiation hardening of V-4Cr-4Ti alloys with different yttrium (Y) contents were studied by self-ion at 550 °C via TEM nano-indentation test technology. The peak damage the V-4Cr-4Ti-xY alloy (x = 0, 0.1, 0.5, 1, wt.%) irradiated 2.5 MeV (V2+) is 8 dpa. Dense dislocation loops observed in all vanadium samples after irradiation. With increase Y content, both average size num...

Static indentation tests on carbon fibre reinforced laminates have been frequently used in literature to predict the value of penetration energy for the laminate. The mechanical set-up most commonly employed involves the use of indentors of diameter comparable with that of the impactors prescribed from standards for falling weight impact, such as ASTM D3763.The specimen is simply supported usin...

This paper presents a constitutive modelling technique for the multi-phase transformations in mono-crystalline silicon under complex loading. The development is based on the physical mechanisms observed experimentally and the incremental theory of plasticity. The stress–strain relationship is derived using closed loading/unloading surfaces, associated flow rule and isotropic hardening rule, to ...

Abstract The main aim of this research work was to conduct an experimental study self-healing capability the composite material by using phase changing material. utilized “paraffin wax” for healing made up carbon fiber and epoxy. Three combinations reinforced epoxy with materials were prepared i.e., plain without any material, paraffin wax nano graphene. fabrication inside capsulation has been ...

A thermal stress range analysis of tungsten-rhenium thin film thermocouples based on ceramic substrates is presented to analyze the falling off and breakage problems caused by the mismatch of the thermal stresses in thin film thermocouples (TFTCs) and substrate, and nano-indentation experiments are done to measure and calculate the film stress to compare with the simulation results. Optimal des...
