Summer Internship - Material design

Purpose
Composite materials consisting of a hard ceramic phase, traditionally tungsten carbide, and a ductile metallic binder phase, most often Cobalt, are generally called hard metals or cemented carbide. Cemented carbides are manufactured through a powder metallurgy processing route - wet milling, spray draying, compaction, and sintering.
Cemented carbide has an attractive combination of properties with high hardness and toughness. To tailor the properties needed for the application e.g. grain size and binder content can be adjusted. Furthermore, additional elements and/or phases can be added to improve the desired properties in new material designs.
Job Descrpition
In this project, you will be investigating material designs for cemented carbides to further improve the properties of the cemented carbide. In detail, you will investigate the influence of different material design aspects to tailor the desired properties. Within a given test space, design a test matrix, analyse the material with methods e.g., light optical microscopy and possibly electron microscopy. Most of the work will be carried out in a lab environment and it will largely be carried out independent on your own
Evaluate the materials and use your material science skills to logically draw conclusions.
Evaluate the material and analyse phases / microstructure of the cemented carbide.

Finally, the work will be presented both orally and in writing.
Your Profile
You are preferably a master’s student within the field of Materials Science, Physics or Chemistry. Previous experience of lab work is meritorious. Since we are a global business, you have excellent communication skills in English, both in writing and in speaking.
All Seco employees across the globe share our family spirit, along with a passion for our customers and a personal commitment to what we do. For us, it is also clear that our diversities form the best foundation for achieving great results.
