Methods for the determination of the physical properties of materials: density and porosity.

Determination of the surface properties of materials: contact angle, surface energy, tensiometry.

Spectroscopic methods for the chemical characterization of materials: FT-IR, UV-VIS, XRD.

Microscopies: optical, electronic SEM, TEM, atomic force AFM, confocal.

Determination of the mechanical properties of materials: status and dynamic methods, tensile testing, compression testing, impact testing.

Fatigue and wear.

Spots of fracture mechanics.

Thermal and thermomechanical analysis: TGA, DSC, DMTA.

Module of Laboratory of Materials Characterization (24 hours)

Tests for the investigation of the nature and microstructure of materials (absolute and bulk density, water absorption, mercury intrusion porosimetry, laser grain size distribution analysis, SEM + EDX, abrasion test, XRD, etc.).

Tests for the investigation of the mechanical properties of materials (strength test, impact test, hardness test, etc.).

Tests for the investigation of the thermal properties of materials (DSC, TGA, dilatometry, etc.).

Teaching methods

Module Materials Characterization M: (24 hours)

Frontal lectures.

 

Module of Laboratory of Materials Characterization (24 hours)

 data and interpretation of the results with relation to the properties of the investigated materials. The theoretical support of this Course is represented by the “MATERIALS CHARACTERIZATION” Course.

Assessment methods

Module Materials Characterization M: (24 hours)

Oral examination on the program.

Module of Laboratory of Materials Characterization (24 hours)

During the main experimental activities in the laboratory, students have to complete a sheet.

Final oral test.

The final test will evaluate the achievement of the teaching objectives:

- Understanding of the main investigation techniques for the determination of the nature and the microstructure of materials, along with their results.

- Understanding of the main investigation techniques for the determination of the mechanical and thermal properties, and of the possible results for the different materials classes.

The final grade is based on the average of the grades in three questions on topics concerning the teaching objectives.

The test dates for the whole year and the registration lists are available on-line on the official AlmaEsami website (the lists are closed 48 hours before each exam date).

Teaching tools

Laboratory training on the tests for materials characterization. Tests will be carried out on the most significant typologies of materials with relation to the test itself and the engineering applications of materials.
