Abstract
1,183,476. Alloys. INSTITUT DR. ING. REINHARD STRAUMANN A. G. April 20, 1967 [April 22, 1966], No.18161/67. Heading C7A. In a method of producing a metallic, paramagnetic material of cubic or hexagonal crystal structure having a temperature coefficient of the modulus of elasticity between -10<SP>-4</SP> and +10<SP>-4</SP> per degree C., components of the material are so selected that the material exhibits an atomic paramagnetic susceptibility greater than 50.10<SP>-6</SP> emE/g-atom at room temperature and a negative temperature coefficient of the susceptibility, the components are melted together, and a preferred orientation of the crystals is produced by at least a mechanical or a thermal treatment of the material, said preferred orientation, when the structure is cubic, being defined by the mean value of the product sum of the direction cosine taken over all the crystal orientations with respect to the stress direction, the value being greater than 0À2 for the elasticity modulus and less than 0À2 for the sheer modulus, and said preferred orientation, when the structure is hexagonal, being defined by the mean value of the direction cosine taken over all the crystal orientations between the hexagonal axis and the stress direction, the value being less than 0À25 for the elasticity modulus and greater than 0À25 for the shear modulus. Specified mechanical and thermal treatments are drawing, rolling and annealing. In an example, Nb/10-40% Zr is rapidly cooled from 1000C., cold-drawn, and heated at 550 -600 C. Other specified alloys are (a) Nb/2-10% Cr, (b) Nb/40 atom % Ir, (c) Re/33 atom % W, and (d) Rh/33 atom % Ca. Uses. Vibratory elements such as spiral springs and tuning forks, electro-mechanical filters, and components required to retain rigidity over wide temperature ranges such as in turbines, aircraft and rockets.
