Effect of thermo-mechanical treatment on the evolution of microstructure and mechanical properties in a β and a β rich α+β titanium alloy
Near β and metastable β-titanium alloys are difficult to process due to narrow processing window. Lower processing temperature causes difficulty in recrystallization of these alloys especially in the two phase conditions, ... -
Effect of Thermomechanical Processing on Microstructure And Microtexture Evolution in Titanium Alloys
(2017-09-26)The properties of titanium alloys are based on alloy compositions and microstructures that consist of mixtures of the two allotropic modifications of titanium, the low temperature α (hcp) and the high temperature β (bcc) ... -
The Effect Of Viscosity On The Erosion Of Gradient- Zone In A Laboratory Solar Pond
(Indian Institute of Science, 2006-08-24)Double diffusive phenomena occur in many natural systems and in a variety of engineering applications, such as solar ponds. In a solar pond, the erosion of gradient zone due to convection and diffusion is the main cause ... -
Effective Property Estimation of Carbon Composites using Micromechanical Modeling
