Development and characterization of Al–Li alloys
TL;DR: In this article, a new technique of Li addition has been adapted, which gives maximum recovery of Li in the billet, using this technique, aluminium-lithium alloys of two different grades for aerospace application were cast.
Journal ArticleDOI
Strain hardening of Titanium alloy Ti6Al4V sheets with prior heat treatment and cold working
TL;DR: In this article, the effect of prior cold working before tensile testing has been studied at four different strain rates (10 −4 to 10 −1 ǫ s −1 ) under tensile loading at different heat treatment conditions viz. mill annealing (MA), recrystallization anneeling (RA), solution treatment (ST), and solution treatment and aging (STA).

Vector shift functional unit for successively shifting operands stored in a vector register by corresponding shift counts stored in another vector register
TL;DR: In vector supercomputer processors, the vector shift functional unit as mentioned in this paper shifts the operands of a vector register by an amount equal to the value of the shift count of each operand.
Journal ArticleDOI
Hot workability of γ + α2 titanium aluminide: Development of processing map and constitutive equations
TL;DR: In this paper, a hot isothermal compression test is carried out on reaction synthesized and homogenized titanium aluminide alloys at different temperatures and strain rates using Gleeble thermomechanical simulator.
Journal ArticleDOI
