2784.     REGNER, A.  Magnetometric Determination of the Curie Points.  Jour. Iron Steel Inst. (London), Advance Copy, No. 6, 1930, 22 pp.; Chem. Abs., vol. 24, 1930, p. 5695.

        A low-frequency magnetometer and 2 high-frequency magnetometers suitable for detecting transformation points in steel are fully described.  These instruments gave clear indications of the A₂ point and cementite changes both at 60° and 210°.  Irregularities were observed at the temperature of the pearlitic change.
