Acoustical Properties of Magnetostrictive and Metallic Materials for Naval Applications.
Abstract
Experimental work is described concerning plastic flow in magnetic metals, particularly wire samples of nickel and iron. Plastic flow has been induced by the combined action of ultrasonic and static stressing. The resulting behavior of magnetic permeability, residual stress, electrical conductivity, separated acoustic loss mechanisms, and separated elastic Lame constants have been investigated. Measurements of the plastic strain limit of nickel are presented, as are measurements of stress combinations required to produce plastic flow in nickel. Time dependent phenomena, such as the elastic behavior of samples after plastic flow are also presented. Some conjectures on practical applications of the work are presented. (Author)
