THE EFFECT OF LONG-RANGE ORDER ON THE ELASTIC AND PLASTIC PROPERTIES OF ALLOYS AT ELEVATED TEMPERATURES

Abstract

The dynamic elastic modulus of alloys near stoichiometric CuZn, FeCo and Fe3Al were measured using transverse vibration of unrestrained cylindrical specimens. Test frequencies were in the range 700 to 3000 c. Internal friction measurements were made concomitantly using both the free-decay and half-width methods. Measurements on CuZn were in vacuo using a novel radiation heating furnace. Experiments on FeCo and Fe3Al were in air with an applied magnetic field of 1500 oersteds to eliminate magnetic damping phenomena. Creep studies on CuZn were conducted in compression and on FeCo in torsion. (Author)
