Metallic Materials Shaping Technologies


The curricular unit’s main objective is to confer to the student a solid knowledge about the metallic materials shaping technologies and processes, as well as their positioning in the general scheme of processing technologies.

Taking into account the structure-properties relationships governing material’s behaviour, the student should be able to identify the relative advantages and limitations of the processes, to understand the functioning of the machinery used to implement those processes, and to understand the influence of the various process parameters. Thus, he/she should be in a position to adequately select the best technologies to be used to produce a given part, planning the sequence of processing steps of the material as a function of its properties as well as of the intended application; also, the student should be able, when presented with a defective processing result, to evaluate the possible causes for error and to correct them.

Teaching method

Two types of lessons will be considered: Lectures and laboratory. Lectures will be given using PowerPoint slides, students having access to copies on the course page in the Moodle platform. The laboratory work will be performed by the students under the guidance of the teacher and focus on the different topics of the syllabus.

A series of visits to industrial plants dedicated to metallic materials processing may complement the unit.

Teaching has theoretical and experimental components that will allow students to acquire and apply knowledge to determine the possible processing routes to produce a metallic part. In lectures, the subjects will be presented and explained, which will allow the consolidation of knowledge that will later be put into practice in labs. Thus, lectures and laboratory classes complement each other in order to provide an integrated learning. Lab works assume an important role in the evaluation of the curricular unit as it is through these that students acquire skills that will allow them to master the different technological routes for metal shaping, as well as the effects of processing on the final part’s structure and performance. Study visits are designed to facilitate the transposition of acquired knowledge to an industrial environment.

Throughout the semester, a constant demand will be placed on knowledge previously acquired (Physical Metallurgy and Metallography, Mechanics of Materials I), and special care will be taken in order to establish firm bridges to subsequent curricular units (Thermal Treatments and Mechanical Treatments, Composites – Materials and Applications, Materials Selection).

Evaluation method

Two tests, lab reports, final exam.

 Participation in lab sessions is mandatory, and must be accompanied by the submission of reports, in order to obtain frequency of the curricular unit.

The tests are not obligatory, but should be undertaken to insure exemption from the final exam; a minimum average mark of 9.5 is required to insure exemption from the final exam. If this condition is not fulfilled, the student must submit to the final exam.

The final grade (NF) is obtained as:

NF = 0.30* T1 + 0.30 + T2 + 0.40* P (for the case of exemption from the final exam) or;

NF = 0.60*NE + 0.40* P (for the case of participation in the final exam).

In the above, T1 and T2 are the grades attained in the mid-term tests, P is the average grade of the lab reports and NE stands for the grade in the final exam.
