Metal science and heat treatment

Description: Studies the structure of metals and the formation of the structure of metals and alloys, as well as technology of heat treatment of ferrous and non-ferrous metals. After studying the discipline, the student must competently use the acquired basic knowledge in solving practical problems in the field of metallurgy, to know and understand the mechanisms of plastic deformation and the effect of heating on the structure and properties of the deformed metal.

Learning outcome: knowledge and understanding

• - the formation of the structure of metals and alloys during crystallization; - mechanisms of plastic deformation and mechanical properties of metals; - the effect of heating on the structure and properties of the deformed metal; - iron and its alloys, theory and technology of heat treatment of steel; - compositions, properties and grades of structural and tool steels; - structural non-ferrous metals and alloys, their properties.

Learning outcome: applying knowledge and understanding

• read the state diagrams of metals and alloys; - distinguish structure and determine phases in metals and alloys; - conducts heat treatment of metals and determine the mechanical properties; - choose structural materials by grade of metals and alloys

Learning outcome: formation of judgments

• - in the process of training, students form stable concepts about the basic theoretical laws of technological processes.

Learning outcome: communicative abilities

• - develop the communication skills necessary for teamwork.

Learning outcome: learning skills or learning abilities

• - wisely use the acquired basic knowledge in solving practical problems in the field of metal science. - choose heat treatment modes to obtain the necessary structure and properties of steel and alloys

Teaching methods

1) Technologies of traditional educational activity (lecture and seminar) 2) Technologies of quasi-professional activity 3) Technologies for educational and professional activities 4) Technologies of developing education 5) Differentiated learning technology 6) Business game technology

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

The evaluating policy of learning outcomes by work type

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

• 40% of the examination result;
• 60% of current control result.

The final grade is calculated by the formula:

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
