PROFESSIONS IN SCIENCE AND TECHNOLOGY (MST1)
(Faculté des sciences et de la technologie UNIV-BBA, 2025-06) DJENDEL MOKHTAR
The course "Professions in Science and Technology 1" is designed to introduce students of 1st Year Sciences and Technics to the vast array of careers available within the fields of science and technology. It aims to provide insights into various professional roles, the educational paths leading to these careers, and the skills required to succeed in them. Through a combination of lectures, guest speakers from industry and academia, and hands-on activities, students will explore many disciplines in engineering science. The course also emphasizes the importance of soft skills like communication, teamwork, and problem-solving in scientific and technological professions. By the end of the course, students should have a clearer understanding of their career options in science and technology and the steps they need to take to pursue their interests.
Materials Engineering
(Faculté des sciences et de la technologie UNIV-BBA, 2025-06) DJENDEL MOKHTAR
The content of this course was chosen so as to be able to serve as a manual for materials engineering courses intended for 1st year master's students in accordance with the outline and guidelines of the mechanical engineering department.
Teaching objectives
▪ Implement the main heat treatments and the main techniques experimental for the study of structural transformations of metal alloys.
▪ Highlight changes in properties and valuation of materials obtained at the end of the treatments.
▪ Highlight the correlations between behaviors, treatments and structures.
Prerequisites: The target audience must have prior knowledge in: Thermodynamics (understanding of equilibrium and phase diagrams, thermochemistry), notions of mechanics. Metals and alloys.
The course content is presented in several themes subdivided into chapters:
Chapter 1. Thermal Equilibrium Diagram.
Chapter 2. Time-Temperature Transformation (TTT) diagram & Continuous Cooling Transformation (CCT) diagram.
Chapter 3. Classification of Metal Alloys.
Chapter 4. Heat Treatment Theory
Chapter 5. Classic industrial treatments (annealing and quenching,…..) & Thermochemical diffusion treatments (Carburizing heat, Nitriding etc.).
The hourly volume allocated to the course is 37h30min per semester in one lesson per week of 1h30 and a practical work of 1h. The evaluation of acquired knowledge is done in mode: Continuous assessment: 40%; Exam: 60%.
Depending on the means available in the establishment. manipulations are designed as an experimental project combining the material studied, the treatments, and the characterization.
The different manipulations address the following themes:
• The modification of the properties of alloys by heat treatment in the mass and the study of the hardening mechanisms of metal alloys
CORE TECHNOLOGY 2nd YEAR MECHANICAL ENGINEERING
(Faculté des sciences et de la technologie UNIV-BBA, 2025-06) DJENDEL MOUKHTAR
This handout, intended for students in the 2nd year of the common core of technology, aims to:
- Provide multidisciplinary knowledge using different types of materials; metals and their alloys,
ceramics, polymers and composites;
- Allow the student to become familiar with the different shaping techniques (with and without
material removal) of materials used in cutting-edge industrial fields (mechanics, aerospace, naval
aviation, steel industry, medical, etc.).
The approach of this module is based on the relationships between the structure, microstructure,
development, usage properties and manufacturing processes of these materials in the industrial field. It
relates the types of bonds and the different levels of structuring of the material with the mechanical
properties.
Surface Treatments
(Faculté des sciences et de la technologie UNIV-BBA, 2025-01-16) BOUBAAYA Rabah
Surface treatments and coatings currently constitute one of the essential means of improving the functional properties of metals, in particular resistance to oxidation and corrosion, resistance to fatigue in all its forms (mechanical fatigue, thermal fatigue, surface fatigue), thermal insulation, electrical conductivity, resistance to friction and wear, without forgetting the color and appearance, biocompatibility or adhesion of another class of materials (ceramic or polymer). In 2017, they represented between 8 and 9% of the overall turnover of industrial metalworking subcontracting and up to 15% if we include their share in integrated workshops.
Among the different surface treatment processes, it is possible to distinguish four families: structural transformation treatments of mechanical or thermal origin, diffusion or thermochemical treatments, conversion treatments and coatings. The main sectors of activity are automobiles, construction, public works, mechanics, aeronautics and space, weapons, electrical equipment and biomedical.
This handout entitled “surface treatments” is intended for first-year Masters in Materials Engineering students. The aim of this handout is to describe the different surface treatments and coatings based on improved functional properties based on numerous industrial examples. The improvement of these properties is directly a function of the internal health of the deposits or surface layers modified by the treatment. The document will address in a final chapter the different means of destructive and non-destructive control.
It is written in a simplified manner with examples introduced after having given concepts so that the student can assimilate the course content and have a clear vision of its application in the industrial sector.

MECHANICHAL MANUFACTURING
(Faculté des sciences et de la technologie UNIV-BBA, 2025-01-12) BOUBAAYA Rabah
Machining by material removal is one of the processes of mechanical manufacturing. This machining represents the search for solutions that allow obtaining a conceivable part at a cost with good performance, by combining information relating to the chronological order of the operations performed, the use of skilled labor, machine tools, tools and equipment requested. This technique also allows us to produce parts with complex shapes and high precision without modifying the characteristics of the machined material. Material removal machining allows for very precise tolerances, which is crucial in many fields, such as aerospace, automotive and tool manufacturing. This process is applicable to a wide range of materials, including metals, plastics, composites and ceramics, making it a versatile technique for many industries. In addition, this method is also used for the repair or refurbishment of damaged or worn parts, thus extending their service life and avoiding the waste of valuable resources. In summary, material removal machining remains an indispensable pillar in modern manufacturing, combining precision, versatility and cost efficiency. This handout entitled "Mechanical Manufacturing" is intended for second-year students of the Academic License in Mechanical Engineering, Mechanical Construction option. It is designed to highlight knowledge of product manufacturing techniques, in particular mechanical products. It is written in a simplified manner with examples introduced after giving notions so that the student can assimilate the content of the course and have a clear vision of its application in the industrial sector.
This document is divided into two parts, the first part of which concerns the theory of metal cutting from the point of view of cutting materials, geometry of cutting tools, chip formation mechanism, cutting forces, heating and damage of cutting tools as well as the methodology for choosing cutting parameters.
The second part deals with machine tool technology, based on cutting movements, main components and kinematic chains for some machine tools.
