The non-dendritic microstructure of stircast metals is discussed in terms of the shape stability produced by a high density of growing solid particles. This high density appears to be due to the fragmentation of the initial dendrites. The model of fragmentation due to the formation and subsequent...
Friction stir processing (FSP) is a method for preparing metal matrix composites based on the principle of Friction stir welding (FSW) [15]. The stir tool is used to perform severe plastic deformation, crushing, mixing and thermomechanical treatment on the processed workpiece to obtain the compos...
Yehet al. proposed a classification of the alloys in function of the configurational entropy (ΔSconf). The alloys were classified as HEAs when their ΔSconfat a random state was higher than 1.5 R (R being the gas constant), regardless of whether they are single-phase or multiphase at ...
In this work, we explore the influence of PSD on the microstructural evolution for SS316L printed using the L-DED process by systematically varying powder sizes for a constant set of processing parameters. This controlled investigation from the deposition of single tracks to block samples helps in...

Grain refinement from several millimeters in as-received (AR) condition to the range of 0.35–15 μm was achieved by friction stir processing (FSP). Due to the sluggish nature of atomic diffusion in high entropy alloys (HEAs), the FSP region exhibited an immense variation in microstructure whi...
