1. 1

   CLO 1: Students will systematically master the tripartite relationship between the atomic-crystal structure, phase diagrams, and thermal processing regimes of metals. structural modifications (martensite, bainite, pearlite transformations) during heating and cooling in iron-carbon and other industrial alloys will be analyzed precisely. they will learn to design surface and bulk thermal treatment schemes for materials to meet specific engineering requirements. by the end of the subject, students will acquire the skills to significantly increase the mechanical endurance and operational resource of the material by controlling the microstructural changes.
