FREMGANGSMAATE FOR AA OEKE DEN MAGNETOSTRIKTIVE RESPONS TIL LEGERINGSSTENGER AV SJELDNE JORDARTMETALLER-JERN.

摘要

A short-time heat treatment (viz. 20 to 30 minutes) is employed to improve the magnetostrictive properties of magnetostrictive rods. The rods may be in the form of axially-aligned single crystals or polycrystals. The heat treatment is at a temperature of from 870 to 1100 DEG C, and is followed by cooling to room temperature.
