Offer Description

INEGI-Instituto de Ciência e Inovação em Engenharia Mecânica e Engenharia Industrial announces an open call for one student in the scope of EXPL/CTM-CTM/1528/2021 “In-Situ alloying by laser cladding for high throughtput screening of RCCAs compositions as alternative to Nickel Superalloys”, with the financial support of FCT/MCTES through national funds (PIDDAC), under the following conditions:

Scientific area: Materials Engineering

1. Grant duration and regime:

Duration of 5 months, starting in February 2023. The granting of the scholarships does not generate or entitle a legal-labour relationship, it is exercised under an exclusive dedication regime, and the Scholarship holder is granted the Scholarship Holder Status, in accordance with the Regulation for Research Grants of the Foundation for Science and Technology, I.P., both in their current wording.

2. Work plan:

Combustion processes in jet engines and propulsion systems for aeronautical and aerospace sector would be more efficient, consuming less fuel and reducing CO2 emissions, if they could operate at higher temperatures. Although some high strength superalloys (i.e. Ni-based) show great thermal-chemical-mechanical behaviour, melting point limits their maximum service temperatures to ~1000 °C. Refractory complex concentrated alloys (RCCA), as well as refractory high-entropy alloys (RHEA), have the potential of surpassing state-of-art nickel-based superalloys, since high-temperature properties can be combined with high melting temperatures of refractory elements. These innovative classes of materials are based on three or more refractory metals (e.g. Cr, Hf, Nb, Mo, Ta, V, W, Zr) and commonly other elements, such as Al, Si, and Ti in high concentrations. The main ambition of this project is to accelerate the screening and high temperature characterization of RCCA, while at the same time contributing significantly to their introduction in the industrial field as innovative substitutes for state-of-the-art nickel-based superalloys used under severe conditions in aerospace applications. The attraction but also the challenge of RCCAs lies in its enormous range of combinations in terms of type, number, and amount of elements, resulting in different properties. Laser cladding combined with advanced materials characterization will allow gathering immense new information on RCCA/RHEA and contribute to a better understanding of the interaction between process parameters, alloy composition and structure as well as application relevant properties. Thermodynamical simulation (CALPHAD) will be used as a prediction tool, but also in relation with the microstructure analysis. Within the framework of this exploratory project, RCCAs systems based on MoNbTaW, with additions of aluminium (Al), or vanadium (V) and or zirconia (Zr), will be systematically investigated. For screening purposes, the new compositions will be characterized at room temperature in terms of microstructure, chemical composition and mechanical properties. The three more promising RCCAs compositions for aerospace applications will be tested at high temperature (T>1000 °C). At the end of this exploratory project is expected to increase the practical knowledge of RCCA by sharing scientific and technological breakthroughs regarding the relationship between composition, simulation, processing, structure, properties.

Task 1: Simulation-assisted design of RCCA from MoNbTaW system with the addition of X= Al, Zr, V through CALPHAD.

Task 2. In-situ alloying by laser cladding, process parametrization.

Task 3. RCCA characterization (chemical, mechanical and microstructural), application and optimization of heat treatments.

3. Scientific supervision:

Prof. Doutora Elsa Sequeiros.

4. Admission requirements:

To be enrolled at a master degree.

5. Academic Qualifications:

Students attending the master's degree in Materials Engineering.

 The following are preferential conditions for the evaluation of candidates:

  • Software-based skills based on CALPHAD system;
  • Knowledge of metallic materials characterisation techniques and mechanical tests;
  • Portuguese and English languages: high priority, good level.

Academic degrees obtained in foreign countries shall be registered by a Portuguese institution, according to the DL 66/2018, of August 16th, and the Ordinance nr. 33/2019, of January 25th. It is mandatory to present the certificate to sign the contract.

More information is available on: https://www.dges.gov.pt/pt/pagina/reconhecimento.

6. Monthly allowance:

The scholarship amount corresponds to €875,98 according to FCT (https://www.fct.pt/apoios/bolsas/valores), I.P.  The scholarship payment will be made by bank transfer.

7. Other benefits:

Voluntary Social Security reimbursement, corresponding to the 1st level of the contributory base (for scholarships lasting 6 months or more); Personal Accident Insurance.

8. Applicable Legislation:

Research Fellow Statute, approved by Law No. 40/2004 of August 18, in the current wording published by Decree-Law No. 123/2019 of August 28; Regulation of Research Grants of the Foundation for Science and Technology, I.P. in force (Regulation No. 950 / 2019 of 16 December https://www.fct.pt/apoios/bolsas/regulamento.phtml.pt).

9. Evaluation criteria:

i) Materials engineering student - 30%.

ii) Average of concluded CUs - 20%.

iii) Experience in the subject of the work program - 50%.

10. Composition of the evaluation panel:

Prof. Elsa Sequeiros (President). Prof. Ana Rosanete Reis, Dr. Rui Amaral; (Members). Dr. João Carlos Pereira (Substitute).

11. Publication/notification of results:

After being notified, candidates have 10 working days to submit a formal rebuttal by email (gestao.pessoas@inegi.up.pt).

12. Submission of applications:

Applications must include the following documents:

- Motivation letter, stating the adequacy of the curriculum to the position;

- Curriculum Vitae;

- Qualifications certificate; if possible, the qualifications certificate should be accompanied by the marks obtained in all courses taken. In case of academic degrees awarded by foreign higher education institutions, and in order to ensure the application of the principle of equal treatment to applicants holding foreign and national academic degrees, it is mandatory to recognize those degrees and convert the respective final classification into the Portuguese classification scale.

13. Expressions of interest should be sent between the 26thof January and 08th of February 2022 through the official INEGI website www.inegi.pt in join us | Research Grants by pressing ApplyBI LiRAs UTAF 05/2023.
