Goal

• The purpose of the discipline is to study the theoretical foundations of obtaining sintered and composite materials and products based on them, to develop skills of independent professional activity in the field of materials science of sintered and composite materials made by powder metallurgy.

Objective

• The objectives of studying the discipline are to know the main directions of development of powder metallurgy, analogues and competitors of powder metallurgy technology; the relationship of the structure and properties of sintered and composite materials, as well as ways of their directional regulation; methods and technological aspects of the processes of obtaining sintered and composite materials, including charge preparation, molding, sintering of powder-based products; devices, the principles of operation and operation of machinery and equipment for the main stages of production.

Learning outcome: knowledge and understanding

• The student should have an idea of the main scientific and technical problems and prospects for the development of metallurgy, including powder metallurgy. These views of the graduate should be formed in the light of global trends in scientific and technological progress in metallurgy using powder and composite materials and products made from them.

Learning outcome: applying knowledge and understanding

• The acquired knowledge should be applied in the development of technological schemes; justification and selection of the production method, raw materials; when calculating the conditions for obtaining powders of sintered and composite materials; when preparing raw powders and materials for molding and sintering processes; when determining the properties of the resulting powders of sintered and composite materials and products based on them; when choosing modes molding and sintering.

Learning outcome: formation of judgments

• Possess a culture of thinking, generalize and analyze the theoretical and technological provisions of powder metallurgy, choose the most effective methods and methods of performing professional tasks.

Learning outcome: communicative abilities

• Be able to work in a team, communicate effectively with the team, management. Be able to listen and understand people, influence them, establish good personal and business relationships with them.

Learning outcome: learning skills or learning abilities

• Independently determine the tasks of professional and personal development; engage in self-education; organize their own activities based on the goal and ways to achieve it.

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:
