a X-ray diffractograms of the oxide mixture before and after H2-based redox alloying in the tube furnace. b Photographs showing the geometrical changes of the gal-cast part. c Comparison between theoretical shrinkage calculated from oxide reduction and the experimentally measured value. d Optical micrograph (left) and SEM-EDS maps (right) showing the dense microstructure decorated by Al- and Si-based particulates.
