Abstract
The effect of carbon and hydrogen on the martensitic transformation of Fe-Ni base alloys is studied in this paper. The results obtained between room temperature and -185°C by two different methods based on burst phenomenon and also by quantitative metallography are presented. The influence of carbon on the amplitude of the burst and the dynamic properties of the athermal transformation are connected with mechanical characteristics of the structure. Finally hydrogen influence on Ms temperature and on martensitic transformation is discussed.
