But materials of low absorption or mixed phases show a weak absorption contrast at there interfaces.
This is in analogy to the behaviour of visible light in transparent materials e.g. lenses or prisms.
Therefore the novel X-ray refraction technique might help accelerating materials development, leads to a better understanding of meso-structures and partly replace micro analysis and mechanical testing in advanced materials science.
