An Experimental Investigation on the Mode of Slip in Face-Centered Cubic Metals

The changes of saturation of magnetization of the ordered Ni_3Mn and Pt_3Co alloys caused by plastic deformation were used as the criterion to decide whether the slip in metals is "homogeneous" or "inhomogeneous", i.e., whether it takes place in atomic steps on many successive atomic planes or in large steps on widely separated single atomic planes. It was found that in the ordered Ni_3Mn alloy, the saturation magnetization decreases with the amount of elongation at room temperature, while in the ordered Pt_3Co alloys, the intensity of magnetization at temperature near the Curie point increases with the amount of compression. These changes, which are roughly proportional to the amount of deformation, are probably understood only from the point of view that new disordered regions with Curie point different from that of the ordered state are produced during the deformation, being associated with homogeneous slip on successive atomic planes.
