A simple, compact device was developed for studying phase changes at elevated temperatures. The need for coolant and/or vacuum was eliminated by making the primary and secondary coils of platinum wires wound on machined ceramic insulators. The materials used for the device permit a temperature capability of up to at least 1150°C in air. Typical results are presented from simultaneous measurements of magnetic and dilatometric changes occurring during the heating and cooling of a maraging steel specimen over a temperature range from ambient to 815°C.
