It is well known that, the metallurgy has been honored as “the father of chemistry”. However, the metallurgy as an independent discipline was only established around the Second World War. Why does it take so long for this period? That is because for any matured science a quantitative description is required instead of a qualitative description. Most metallurgical systems are with large number of components and higher melting points that are difficult to be dealt with theoretically. As a result, the empirical treatment will be adopted instead of a theoretical model. There are two kinds of theoretical treatments: physical model and phenomenological model. The former one has a very clear physical picture but it is difficult to be treated. The later one is easy to deal with due to less number of variables. As a result, many metallurgical problems will be solved by using the later theoretical models. In this presentation, it will be shown that how we apply the phenomenological models to solve the metallurgical problems both in theoretical topics and technical aspects.
