Develops innovative model for manufacturing

Published: 26 March 2019

Two PhD students in Material Mechanics, Marie Anna Moretti and Biswajit Dalai, will work in the EU project ENABLE, European Network for Alloy Behavior Law Enhancement. The purpose of the project is to develop an innovative constitutive model for manufacturing so that production time and costs are reduced while the material's performance is improved.

In ENABLE, Luleå University of Technology collaborates with three universities in France, a university in Spain and twelve European companies, including the Swedish companies GKN Aerospace and Sandvik Coromant. In the project, the PhD students will link the metallurgical aspect to the mechanical properties of the material, for example its ability to withstand stress at different high temperatures. The materials studied are used in demanding high-tech areas such as the aerospace industry.

– The purpose of the ENABLE project is to be able to predict the final mechanical state of a metallic structure at the end of the manufacturing chain. I will examine titanium and nickel alloys under different conditions of temperature and strain state, says Marie Anna Moretti, PhD student in Material Mechanics at Luleå University of Technology.

Control over the manufacturing process

Using updated methods for process simulations, components containing titanium, nickel and aluminium alloys should be manufactured in a way that makes them better, cheaper and lighter. By tailoring the material's microstructure, it is possible to control the mechanical properties of the material. The result is that the component's performance increases while production time and production cost are reduced.

– When the project is finished, we hope to have a model that can predict the mechanical state of a structure after several manufacturing processes. For my own part, I want to produce effective material models for titanium and nickel alloys for a wide range of temperatures and load speeds. We will have control over the entire manufacturing process, which will lead to better control over the quality of the construction, says Marie Anna Moretti.

Look forward to research exchange

As mentioned, the project includes several European partners and an important part of the project is an exchange structure in which the researchers visit the other universities and companies to learn from each other.

– I look forward to working with experts in academia and industry in mechanics, material science and numerical methods. For ten months, I will participate in an exchange with the other parties in the project. That will give me the opportunity to experience different cultures and the requirements that exist in the private sector, says Biswajit Dalai, PhD student in Material Mechanics at Luleå University of Technology.
