Johan Ahlström's research concerns the behaviour of engineering metals both during production and in service. Experimental characterisation of the deformation behaviour and its relation to microstructure, temperature and strain rate combined with numerical modelling give possibilities for physical interpretation and prediction of the behaviour in a certain environment. Johan is also interested in connected phenomena like phase transformations, fatigue, residual stresses and crack growth. Methods used include biaxial mechanical testing, dilatometry, X-ray tomography and diffraction, microscopy and spectroscopy. Examples of industrial aims are decreased maintenance costs and increased reliability of railways as well as decreased fuel consumption in combustion engines.
