Materials Physics
FSI-5FM Acad. year: 2022/2023 Winter semester
The purporse of the course "Physics of materials" is to give to students necessary teoretical basic of turn-key solution of material problems. The main issue of this course is physical basis for manufacturing technologies of metalic constructional materials i.e. shanking, welding, cutting and founding. It includes phisico-chemical basic of production and treatment of ceramic and macromolecurlar materials as well as. In this way it creates cross-disciplinary structure with technologies of non-metalic materials. It gives information on deformation and fracture behaviour of materials, failure mechanisms and fracture mechanics bases. The knowledge of these course is presumtion of creative work in the field of engineering science i.e. engineering nad casting technology and engineering materials.

Learning outcomes of the course unit
This course allowes students to obtain knowledges about inner structure of constructional materials and about thermodynamic and kinetic aspects of their phase transformations. In the course will be lectured destcription and law suits of diffusional process with reference to given phase transformations.Studets get knowledges about deformation and fracture behaviour of materials,fracture mechanics bases and selected processes of degradation (corrosion,abrasion)as well as.
Prerequisites
The course continue knowledges from atomic composition field, chemical thermodynamic, electrochemistry, crystalline composition of metals, equilibrium and disequilibrium phase transformations focused on metal systems, deformation and fracture behaviour of materials and knowledge of structure and properties of basic groups of metalic and nonmetalic materials
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
Students have to take part in all practices, to give over all protocols of laboratory practices which have to have commensurate scientific and graphic form and student have to elaborate final semestral thesis which will be include in the exam clasification. At the exam will be checked knowledeges of given topics mainly ba written form. Topics will be notified to students in the begining of the course.At the verbal part of the exam student will answer question for other knowledges verification. Final clasification includes: protocols valuation, and result of the written an verbal part of the exam.
Aims
The aim of this course is to notify students of inner structure of real crystalic and amorphous materials (metals, polymers, ceramics)and of the influence of defects interaction and circulation on their material manufacture qualities and technological properties. The task of this course is to give knowledges about relationship among phase composition, material transformations and mechanical and brittle failure properties.
This subject is included into study plan of 3rd year of general bachelor's study as a compulsory-optional one. It is recommended as a prerequisite of branches M-KSB or M-MTL.
Specification of controlled education, way of implementation and compensation for absences
Participation in practices is mandatory, must be properly excused absence, the basic credit condition is continuous giving over proctocols as well as. Knowledges of lectured topics will be checked by short tests. In the case of sik leave in practice given topic will be supplied by individual submission.
