Abstract

The development of a temperature control system based on semiconductor thermobatteries has been used in a set of devices for studying the martensitic transformation. The devices range from a simple stage for an optical microscope to a more elaborated system as a differential scanning calorimeter [1]. Here the attention is placed in this last system. The general problems of the temperature scanning calorimetry are reviewed from the signal theory point of view and the solutions applied to our system discussed. Some measurements are shown as an example of its application.

Zusammenfassung

Zur Untersuchung der Martensitumwandlung wurde in einer Reihe von Apparaturen ein auf Halbleiter-Thermosäulen basierendes Temperaturüberwachungssystem eingesetzt. Die Geräte reichten von einem einfachen Objekttisch eines Lichtmikroskopes bis zu komplizierteren Geräten, wie z.B. einem DSC-Kalorimeter [1]. Vorliegend befindet sich der Schwerpunkt auf letzterem. Es wird ein Überblick über die allgemeinen Fragen der Temperatur-Scanning-Kalorimetrie gegeben, angefangen vom Aspekt der Signaltheorie und der angewendeten Lösungen bis zu dem von uns behandelten System. Als Anwendungsbeispiele werden einige Messungen dargestellt.
