Development and Processing of High Temperature Shape Memory Alloys for airplane actuators applications
Torque Tube Inside Blade Spar
Initial Soft Matrix with Equi-axed Grains and weak Texture
ECAE is superior to the other techniques because of the formation of uniform microstructures, control over the development of grain morphology, texture and ease of process
Strengthened thru Grain-Size refinement, sub-grain formation and specific crystallographic Texture
Will be
At the Shear Zone as high as 116% Strains are applied without considerable change in the cross-section as against 60-70% Strains applied in conventional Drawing operation & results in large processed billets
