Abstract

The strength and mechanical properties of giant magnetostrictive materials fabricated by powder metallurgy and Bridgman method were investigated. The effect of the shape and volume of test pieces on compressive strength and compressive fatigue properties were examined for the powder metallurgy specimens. Test results showed : (1) The compressive strength of the powder metallurgy material specimens (PM) was about 2/3 of the Bridgman material specimens (BM), while the strength scatter of PM was smaller than BM. (2) The radial compressive strength was about 1/20 of the compressive strength, and both kinds of specimens showed brittle fracture features. (3) Specimens of both materials showed nonlinear stress-strain curves, and the modulus of elasticity rapidly increased with increasing stress in the low stress region. (4) The compressive strength of PM was influenced by the shape of specimens : the compressive strength of prism type specimens was lower than that of rod type specimens. However, the strength was not influenced by the volume of specimens. (5) There was an apparent fatigue limit at about 60% of the compressive strength for PM.
