Description

Background:

In Directed Energy Deposition (DED-Arc) processes, producing Metal Matrix Composites (MMCs) can be carried out on ex-situ or in-situ mixing of the matrix and reinforcements. In-situ mixing can be realized in the form of a Hybrid Wire-Powder Approach where the matrix material is fed in wire form, while the reinforcement particles are fed in powder form. Powder feeding position, melt pool temperature control, and reinforcement type is essential to maintain a stable process and to achieve the desired microstructure and relative volume fraction.

Aim:

The objective of this research is to explore different process parameters for the deposition of mild steel reinforced with TiC particles.

Your Tasks:

  • Conducting a literature analysis on the current state of the art in additive manufacturing of MMCs
  • Carrying out a Design of Experiments on single or double tracks
  • Using optimum parameters to deposit larger structures
  • Mechanical and metallurgical characterization of the produced parts.
  • Analyzing the results and conclusions.

 

Requirements

Your Profile:

  • Mechanical Engineering, Material Science or a similar study.
  • Basic knowledge in materials science, metallography, and mechanical testing.
  • Proven experience in CAD/CAM software.
  • Interest in additive manufacturing and practical work.
  • Very good English spoken and written.
