Abstract
The magnetic properties of Co–Fe–Ti alloys in the vicinity of 80% Co‐11% Fe‐9% Ti were investigated. Saturation magnetization decreases nearly linearly with Ti additions, extrapolating to a zero value at about 15% Ti. Values of coercive force up to about 60 Oe could be developed by precipitation aging of arc‐melted alloys containing 8% Ti. Ductile alloys with Hc up to 45 Oe, however, were limited to 6% or less of Ti. For the latter, the coercive force was increased by cold‐working prior to the aging treatment. Wire specimens of an 85% Co‐12% Fe‐3% Ti alloy exhibited excellent squareness and low magnetostriction.This publication has 1 reference indexed in Scilit:
