Abstract : Magnetic investigation of the precipitating systems proved to be a sensitive means by which the structural properties of the alloys could be determined. These structural properties could be examined during the earliest stages of anneal with a degree of precision not possible when standard techniques are employed. Whereas electron microscope and x-ray studies confirmed many of these magnetic findings, further efforts would be desirable in this direction, particularly microscope examination of thin foils to determine particle orientation. The experimental torque magnetometer method for the examination of anisotropy and orientation has proved to be a potentially powerful tool and it would be of continued interest and value if applied to other precipitating alloy systems. This technique has applications which extend beyond the study of precipitating alloys into the field of powder ferromagnetism. (Author)
