ABSTRACT:
A method for making a non-magnetic alloy structure. Alloy samples are for by taking three volumes V1 of host matrix material having a first susceptibility X1 and adding to each of them one of three volumes V2, V3 and V4 of a magnetically compensating material having a second opposite susceptibility X2. The volume V3 is chosen so that (V1)(X1) =(V3)(X2). The volumes V2 and V4 are chosen so that V3/V1-V2/V1 is equal to 0.299 percent and V4/V1-V3/V1 is equal to 0.531 percent. The magnetizations of the alloy samples are determined and ploted as a function of their volume percentages. A volume percentage V5/V1 is determined from the plot, such that the volume percentage, V5/V1, has zero magnetization. This volume percentage V5/V1 is used to make nonmagnetic alloy structures having this volume percentage V5/V1.
