Abstract

An inexpensive five-channel DTA apparatus for educational use is described in detail. It consists of a home-built furnace insert and commercial components including a personal computer for data acquisition and display. The alloy tin/bismuth is proposed for DTA demonstrations in practical courses due to its favorable properties. Results obtained with this alloy and the apparatus described are shown.
