Cerium-based intermetallics are currently attracting much interest as a possible alternative to existing high-performance magnets containing scarce heavy rare-earth elements. However, the intrinsic magnetic properties of Ce in these systems poorly understood due difficulty quantitative description Kondo effect, many-body phenomenon where conduction electrons screen out Ce-4f moment. Here, we sh...

Thermal etching is a method which is able to reveal and characterize grain boundaries, twins or dislocation structures and determine parameters such as grain boundary energies, surface diffusivities or study phase transformations in steels, intermetallics or ceramic materials. This method relies on the preferential transfer of matter away from grain boundaries on a polished sample during heatin...

• Solidification of Al-5wt%Fe alloys was monitored via high-speed synchrotron tomography. Formation dynamics Al 13 Fe 4 intermetallics were revealed. Hole-like defects filled with aluminium melt observed within the intermetallics. Oriented particle attachment as a potential growth hypothesis proposed. High-speed tomography used to investigate nucleation and intermetallic during solidification a...
