This collaborative project between the Avignon Ceramic company and the CEMHTI laboratory aims to optimize the formulation and design of refractory ceramic components used in investment casting and obtained by 3D printing or injection. This study will focus on the one hand on the reactivity of the ceramics of interest in contact with molten alloys during casting and on the other hand in contact with strong bases for their dissolution.
The selected candidate will be in charge of the characterization of the ceramics, the reactivity and dissolution tests as well as the evaluation of experimental data. She or he will have to: • Characterize the ceramics mainly by thermal analyses (dilatometry, TDA, …), structural analyses (XRD) and microstructural analyses (SEM microscopy, TEM) • Carry out reactivity tests with post-test and in situ analyses, i.e. at high temperature • Analyse the exprimental results and propose phenomenological description of ceramic/molten interactions and dissolution • Write reports and scientific publications • Disseminate and valorise the results in the form of communications in conferences and within the consortium.
At the CNRS, within the laboratory "Extreme Conditions and Materials: High Temperature and Irradiation of Orleans - CEMHTI (UPR 3079), the CERAM team is recruiting a post-doctoral fellow motivated by a study of reactivity between refractory ceramic components and molten metal alloys and their dissolution for investment casting applications
The CEMHTI is a CNRS research unit spread over two sites (High Temperature and Cyclotron) with a staff of around one hundred. The laboratory develops expertise and original tools at the national and international level to study the physico-chemical properties of materials under extreme conditions. The researcher will join the CERAM team based on high temperature site and will work in close interaction with many reserchers of the laboratory to use the characterization tools available at the CEMHTI. To complete the characterizations he/she will use the tools of the MACLE platform (SEM, TEM, etc.).
