In the proposed case study the authors show, how the original methodological algorithm may be used to creatively teach basic academic research skills and shape the fundamental research competence of professional literature critical assessment. The didactic technique of key concepts mind-mapping and presenting critical thinking reports by means of cognitive comprehensive reading professional academic literature is going to be demonstrated in the current paper as a creative tool of training analytical skills of critical evaluation, necessary for post graduate students involved in their early research activities.

As part of a broad program on composite materials, the role of the interface on the micromechanics of deformation of metal-matrix composites is being studied. The approach is to correlate elastic behavior, micro and macroyielding, flow, and fracture behavior with associated structural detail (dislocation substructure, fracture characteristics) and stress-state. This provides an understanding of the mode of deformation from an atomistic viewpoint; a critical evaluation can then be made of existing models of composite behavior based on continuum mechanics. This paper covers the electron microscopy (transmission, fractography, scanning microscopy) of two distinct forms of composite material: conventional fiber-reinforced (aluminum-stainless steel) and directionally solidified eutectic alloys (aluminum-copper). In the former, the interface is in the form of a compound and/or solid solution whereas in directionally solidified alloys, the interface consists of a precise crystallographic boundary between the two constituents of the eutectic.
