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.
