From the microstructure of steels to the explosion of sparks
Emergent Scientist, 2019 Sparks ejected by the grinding of steel can be observed to split in mid-flight. In this paper, we investigate the link between steel microstructure and the splitting behavior using two different steels: hypoeutectoid (containing less than 0:8% carbon ...
