Weekly Schedule

1) Engineering Materials and their Properties; examples of structures and devices showing how we select the right material for the job.
2) The Price and Availability of Materials: what governs the prices of engineering materials, how long will supplies last, and how can we make the most of the resources that we have?
3) The Elastic Moduli; stress and strain; Hooke’s Law; measuring Young’s modulus; data for design.
4) Bonding Between Atoms; the types of bonds that hold materials together; why some bonds are stiff and others floppy.
5) Packing of Atoms in Solids; how atoms are packed in crystals - crystal structures, plane (Miller) indices, direction indices; how atoms are packed in polymers, ceramics and glasses.
6) Solidification behavior of industrial iron and non-ferrous materials, basic concepts related to melting and solidification.
7) Solidification and cooling curves of metals and alloys, grain formation during solidification, equilibrium constitution and phase diagrams.
8) Midterm examination/Assessment
9) Explanation of the iron-carbon equilibrium diagram, explanation of steel and cast iron zones on the equilibrium diagram, explication of austenite, ferrite, pearlite, cementite, ledeburit, eutectoid and eutectic concepts.
10) Classification of steels according to micro structures and usage of steels. The effects of alloying elements on steel properties.
11) Classification of cast irons according to internal structures and components and use areas of them.
12) Heat treatments of steels and indication of heat treatment zones on iron-carbon diagram.
13) Widely used non-ferrous metals in industrial areas, usage and selection of industrial non-ferrous metals according to purposes.
14) The steel standards in our country and world. Meaning of these standards.
15) Review of the lesson and general repetition.
16) Final examination
