Personal profile

Biography

Dr Vit Janikis Senior Lecturer in Materials, Mechanics and Measurement at Coventry University. Vit joined Coventry in July 2017 after spending five years at WMG, University of Warwick as Research Fellow in Materials Characterisation. In 2008 during his PhD study at the Czech Technical University in Prague he was awarded the EU Science and Technology Fellowship China and spent two and half years as postdoctoral researcher at School of Materials Science and Engineering, Shanghai Jiaotong University, China. Vit obtained MEng (Dipl. Ing.) in Materials Engineering in 2005 and PhD in Materials Engineering in 2009 both at the Czech Technical University in Prague, Czech Republic.

Research Interests

Vit’s main research interests are in physical metallurgy and characterisation of engineering metals and alloys. By controlling the microstructural response of materials during thermal and thermo-mechanical processing he aims to improve both materials strength and formability simultaneously. With advancement of heated stage electron microscopy Vit’s main scientific achievements have been in the development of characterisation methods to monitor transient stages of metallurgical processing of advanced high strength steels and light alloys (Al, Mg). Vit’s additional interests are in exploiting such improved metals and alloys in specific areas of light-weighting in transportation industry to allow industrial partners to meet the emission reduction targets.

At WMG Vit worked as full time researcher on the EPSRC project “Micro-structuring micro-alloyed steels via non-metallic precipitate formation” (EP/L018632/1). He investigated interphase precipitation during austenite to ferrite transformation and its role on the strengthening and ductility of automotive advanced high strength steels by means of heated stage and site specific methods such as Confocal Laser Scanning Microscopy, Heated Stage Electron Back Scattered Diffraction, site specific Focused Ion Beam lift-out for Transmission Electron Microscopy and Small Angle Neutron Scattering (SANS). Vit’s work within this project in partnership with Tata Steel Europe, University of Manchester and Rutherford Appleton Laboratory Didcot, led to improved strength and hole expansion capacity of XPF800 type ferritic adhanced high strength steels and its successful commercialisation for automotive chassis components.

Also at WMG Vit was a core member of the materials light-weighing theme within Innovate UK High Value Manufacturing project CATAPULT. He acted both as principal researcher and project manager on various light-weighting transportation related projects and collaborated closely with industrial partners including Tata Steel Europe, Jaguar Land Rover, Superform Aluminium UK, Aeromet Int, Ricardo, G.R.M. Consulting; in total grant value of above £950k. Two of his projects Optimization of Thermomechanical Processing of Advanced High Strength Steels for Improved Strength and Formability in Automotive Chassis Components and Preventing Zinc Assisted Cracking during Hot Press Forming of Automotive Galvannealed Boron Steels were selected by CATAPULT centre at WMG as “High Impact Show-Case Studies”.

As postdoctoral researcher at SJTU, China, Vit participated in Key Hi-Tech Research and Development Program of China and won China Postdoctoral Foundation award to study Elevated temperature behaviour and creep resistance of Mg-RE alloys. 

Vision Statement

Silicon gave us computers and with them data, iron gave us machines and with them mobility. So how can we infuse the data and knowledge of the Silicon Age into the processes and materials coming to us from the Age of Iron? A revolution in the way how we visualise materials orrured during Silicon Age, electron microscopy is so powerful that we can see every atom or crystal defect that builds or destroys our materials. A new electron microscopy methods such as correlative microscopy can heat the material directly inside the chamber of the microscope and detect the changes occurring to the material during its processing. Thanks to the Silicon we can now see Iron under the microscope behaving like an organic material, growing, transforming, deforming, or relaxing under our own eyes. The fact that we can see this behaviour and be able to measure it is very important from scientific perspective as we can now design new metallurgical process and materials based on this new way of materials characterization to significantly increase their performance. This can lead to renaissance of Iron, steel and metals and alloys and this project is looking at exploring this possible renaissance in design of new materials for transportation industry.
