Abstract
Diflerential Thermal Analysis (DTA) is one of the thermoanalytical techniques developed for the study of
solid materials and is being extensively used in metallurgy. This provides a sensitive and reliable method
of resolving the fine details of the heating and cooling curves.
New sohd mater~alsp, arlrcularly superlonlcsohds, are formed by sol~ds olut~onsb etween two or more
compounds and undergo phase trans~t~onTsh ese two aspects can be studled from the phasedragram
w~tha knowledge of the trans~t~otenm peratures at varlous compos~t~onofs t he components whlch can be
studled by DTA.
This paper describes the construction of a small, compact laboratory model DTA set up, the working
of which is tested with a few known systems.
Results are also presented and discussed for a new system Agl-TI1 wh~ch is being studied to
understand ~tss uperion character~stics.
