Project Description

A. Introduction and Background:
Regarding governmental regulation, the UK is planning to become the first country to pass a net-zero emissions law. This goal will focus UK industries in achieving net-zero greenhouse emissions by 2050 which electrical vehicles as well as electrical aeroplanes are unavoidable new sectors. Hence, increasing the efficiency of electrical motors is becoming more crucial for consumers as well as the environment. Considering the fast-growing demand for high-frequency electrical motors, there is a need to explore innovative solutions to allow the industry to produce E-steels with the higher levels of Silicon and get the benefit of it. This PhD research aims to develop additive manufacturing (AM) techniques to produce high silicon content E-steel parts with enhanced microstructure in regards with their magnetic applications.

B. Research plan, current challenges and objectives:
The winding core of electric motors and generators is manufactured from laminations of E-steel. This E-steel component is key in transforming electrical energy to mechanical torque in electrical motors and vice versa in generators. From a metallurgical point-of-view, magnetic properties of these materials such as magnetization curves, permeability and specific losses are, largely, correlated with the level of silicon, microstructure and especially crystallographic texture. Another industrial concern in E-Steels, is their poor mechanical properties particularly for the high Silicon content E-steels. To overcome these challenges, a combination of AM and thermomechanical manufacturing processes can help. On this base, the main objectives of this PhD research is as below:

Obj1: To study the feasibility of using AM along with thermomechanical processes to fabricate E-steel components.

Obj2: Microstructural designing and Texture developing of E-steel by optimising AM processes.

Obj3: To demonstrate 3D-printed E-steel parts with high magnetic performance.

Tasks and Responsibilities
• Literature review on microstructural designing of engineering materials through AM and post treatment operations.
• Investigating the correlation between microstructural features of E-steels with the AM parameters and their impact on their magnetic performances.
• Conducting and optimising the AM process along with materials characterizations.
• Generating the technical documentation required all along the work. ”

Supervisor
Dr David Butler, prior to joining DMEM in June 2017, I spent the past 18 years as an Associate Professor at the Nanyang Technological University. In 2011, I was tasked with establishing the Advanced Remanufacturing & Technology Centre (ARTC) which has now grown to over 180 staff. My focus at Strathclyde is the areas of Manufacturing Metrology & Processes and is a joint position with the National Physical Laboratory.
Dr Saeed Tamimi is a research scientist at the Advanced Forming Research Centre (AFRC) where he works on fundamental and applied research including industry-related technical projects. Saeed’s background is material science and manufacturing engineering and the research area of his interest are thermomechanical operations of engineering materials and also material science in AM processes
