Below two figures represent the possible two phase microstructures which may be observed in metallic alloy systems. a) In both case the B (Beta) phase is formed in different shapes. In order to distinquish each situation how we can name the B (Beta) phase ? (5 p) b) Calculate the dihedral angles between a (alpha) and B (Beta) phases (6 p) c) What are the basic parameters leading such diffent microstructures of these metallic alloys ? Explain each of them by mentioning their importance according to basic physical metallurgy principles. (7 p) d) Explain the differences and similarities between "martensite phase in steels" and a "amorphous metal". (12 p)
