About Schlumberger:

 

We are Schlumberger, the leading provider of technology and services to the energy industry. Throughout much of the oil and gas lifecycle in over 120 countries; we design, develop, and deliver technology and services that transforms how work is done.

We define the boundaries of the industry by unleashing our talented people’s energy. We’re looking for innovators to join our diverse community of colleagues and develop new solutions and push the limits of what’s possible. If you share our passion for discovery and want to find out what you could really do, then here is the place to do it.

 

Job Summary:

Additive manufacturing "AM" or 3D printing is a family of processes commonly used to produce components of complex shapes and for various uses in small/medium series (mechanical parts, prototypes, models, etc.). 

For AM components, the material deposition process and its heat treatments often affects the macroscopic mechanical properties and properties of the part. This limits their use as functional components in the case that the service environment is relatively highly corrosive. As part of this project, we propose to study the behavior of components produced by AM process. This study will address both experimental and theoretical aspects by performing tests, characterization and study of behavior. 

 

The study will focus on the experimental characterization, induced damage mechanisms in 3D printed parts. The end goal is to be able to optimize process parameters and heat treatment to improve their corrosion resistance. From experimental data, a deep study taking into account the behavior of AM parts in NACE MR 0175/ISO 15156 and NACE MR0103/ISO 17945 testing environment. 

 

Essential Responsibilities and Duties:

• Study of state of the art in the field of additive manufacturing by L-PBF/DED by analyzing the process, the influential parameters and    the behavior of the materials used for the 3D printing of parts. 

• Analyze the physical phenomena of stress corrosion cracking (effect of microstructure and mechanical, as residual stresses, precipitates, density of dislocations, material behavior, ..) 

• Microscopic and Macroscopic experimental characterizations on test specimens produced under different deposition conditions. The topography of the surfaces will then be assessed to highlight 

the heterogeneities between the specimens and their corrosion behavior. 

 

Qualification:

  • Master’s degree – 2nd year or final year of Engineering School

 

Competencies:

  • Mechanics
  • Materials
