Physical Metallurgy 2

Objectives and competences:

The goal is to deliver the necessary theoretical knowledge (supported with practical examples) to to a student in order to enable him/her to understand the relationship between the physico-chemical properties of elements and their interactions in the alloying systems. Students learn and acquire skills in the field of physical metallurgy, which deals with the issue of the constitution alloying systems and heterogeneous equilibrium solidification, solidification processes, precipitation hardening, changes and physical-metallurgical processes in the solid and the resulting structure of metallic materials.

Knowledge and understanding:

Declarative knowledge: To learn and understand the principles of physical metallurgy governing the properties and behavior of metallic materials on a higher level. Students should achieve the level of knowledge in the field of physical metallurgy (both theoretical as well as practical) that will make them competent in understanding and influencing the concept structure-properties-purpose.

Content (Syllabus outline):

The structure of metallic materials and its characteristics in relation to the properties and possibilities of its characterization using modern methods in general (TEM, HRTEM, STEM, AFM, XPS, AES, DSC, etc..) Structure of the third state of matter-quasicrystalline and evaluation of achievements in the field of metallic glasses. Dislocations, twinning and deformation. Recovery and recrystallization. Solid solution and substitutional and interstitial diffusion. Solidification of molten metal. Nucleation and growth. Physico-metallurgical basics of binary and ternary alloying systems. Phase equilibria (reactions and transformations) that occur in these systems. Physico-metallurgical fundamentals and thermodynamic characteristics of reactions features of eutectic, peritectic, monotectic, metatectic, sintectic type and practical examples of technical alloys. The treatment of transformations in the alloying systems in solid state (eutectoid, peritectoid, metatectoid etc. transformation), examples of decomposition and ordering processes. Martensite transformation. Precipitation and hardening. Scheilova forecasting method based on the CCT diagrams, TTT diagrams. Presentation of the basic constitution of alloying forecasting systems based on physico-chemical properties of chemical elements. Modeling building alloying systems and phase equilibria prediction using software packages.
