The main competencies at the department of Industrial and Materials Science are found in the areas of: Human-Technology Interaction | Form and Function | Modeling and Simulation | Product Development | Material | Production and in the interaction between these areas. The research develops the industrial process, from need to finished product while creating added value. To combine skills throughout the whole chain distinguishes the department both nationally and internationally. Here we gather internationally prominent researchers, in dynamic and outstanding research environments, as well as in national and international research networks.

The Division of Materials and Manufacture

The Division of Materials and Manufacture at the Department of Industrial and Materials Science consists of three research groups (Surface and Microstructure Engineering, Powder and Surface Technology and Manufacturing Technology). The research activities span from basic research on nanostructured materials to product- and process related issues within materials and manufacturing technology. The research is carried out in close collaboration with national and international industries and universities. Our graduate as well as undergraduate education is organized in a wide range of courses, including the masters programme on Materials Engineering. The group is also the host and leader for the national Competence Centre for Additive Manufacturing – metals (CAM2), with more than 20 companies involved and a long term research agenda. CAM2 is the only national centre on additive manufacturing and one out 8 new competence centres Sweden supported on long-term by Vinnova. Powder Technology Laboratory (PTL) at San Diego State University, California, USA is the key research partner of the CAM2. PTL’s associates are currently undertaking projects on various research topics includingfundamental research on the emerging field-assisted sintering technologies (such as spark plasma sintering, flash sintering, high voltage compaction, etc.), additive manufacturing of metals, ceramics, glass, and composite materials, and multi-scale analysis of various powder processing techniques.

Information about the research and the project
Additive manufacturing (AM) or 3D printing is rapidly growing technology. So far, international efforts been mostly concerned with hardware development, while materials development and powder technological issues are still important to solve to boost the technology further. Binder jetting is an additive manufacturing process in which a liquid bonding agent is selectively deposited to join powder particles. The printed part (green part) is dried, debinded and further sintered in order to assure required mechanical performance of the component.

The research in the area of additive manufacturing at the division of Materials and Manufacture is based on the competence within the Powder and Surface Technology Group, within which development of powder metallurgical materials is a key activity. The research involves the application of advanced additive manufacturing processing with following materials characterization to understand the development of the properties and microstructure of the final component. The Division has access to required resources in additive manufacturing and advanced characterization, including techniques like analytical electron microscopy (SEM and TEM), surface analysis (Auger and XPS), in combination with all necessary complementary techniques (XRD, thermal analysis, etc.). The group performs both basic and applied research, and materials investigated include both structural and functional materials.

Powder Technology Laboratory at SDSU is the leading group on advanced powder technologies and simulation of the sintering process. The group has developed in-house methods and tools for simulation of the sintering processes and resulting effects on the component geometry and properties which are of vital importance for industrial implementation and integration of the AM technology.

The PhD student work proposed is of interdisciplinary nature and combines processing of the components utilizing state-of-the-art binder jetting technologies and advanced material characterization in combination with the dedicated simulation of the sintering process.

The PhD student project proposed will be performed in both Chalmers University and SDSU in close collaboration with industrial partners of the CAM2 centre – Höganäs and Sandvik.

Major responsibilities
Scientific and technological challenges are to understand how materials’ types, components design and processing conditions will affect the final component properties (microstructure, surface and mechanical properties, final geometry, etc.). The main method addressed is binder jetting and research questions of interest include the effects of powder properties on the components’ performance as well as the basic understanding of the sintering process in case of the complex components produced by binder jetting.

The PhD study will be divided into two equal time periods between Chalmers and SDSU, two years in total at each research organization. During first year at Chalmers the candidate is supposed to work on binder jetting technology with focus on manufacturing of the components with following advanced characterization in order to acquire the required experience and data input for the following simulation and fundamental experimental work at SDSU. During years 2 and 3 PhD research work will be focused on simulation and fundamental experiments of the sintering processes at SDSU. During last year at Chalmers, experimental validation of the developed fundamental concepts will be performed and PhD Thesis summarized. PhD work will be supervised by both, Chalmers and SDSU, and will be defended at Chalmers. The proposed time plan is preliminary and may be modified in the course of the PhD study.

The candidate is expected to obtain a PhD degree in about 4.5 years. The major responsibilities of the candidate are to pursue own doctoral studies. Candidate is expected to develop own scientific concepts and communicate the results of the research performed verbally and in writing, both in Swedish and in English. The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 15 to 20 percent of working hours.

Position summary
Full-time temporary employment at Chalmers with the special conditions during the stay at SDSU. The position is limited to a maximum of five years.

Qualifications
We are looking for a highly motivated and independent candidate with MSc degree corresponding to at least 240 higher education credits in a relevant fielda warded by an internationally recognized university in materials science, metallurgy, mechanical engineering, physics, chemistry or relevant subjects. Experience and good knowledge in materials science and FEM simulation are required. Additional knowledge and experience in characterization techniques, materials synthesis and processing are considered as advantages. All the skills mentioned above have to be clearly indicated in the application and confirmed, if possible, by supplementary documentation (MSc Thesis, journal papers, course certificates, reference letters, etc.). Interest and curiosity in the subject as well as good analytical skills are required. Good communicative and collaborative skills are required; the applicant is also expected to be proficient in both verbal and written English. 

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
