• Progress in modelling solidification microstructures in metals and alloys. Part II: dendrites from 2001 to 2018 (2020, background): “The e ff ect of the misorientation of grain boundaries re fl ecting the transition between attractive to repulsive behaviour as the misorientation is increased above 13 deg. has been clearly demonstrated by the development of hot cracks in laser welding of Ni-based bicrystals [309] (Figure 30).”
• Hot cracking mechanism affecting a non-weldable Ni-based superalloy produced by selective electron Beam Melting (2018, background): “[2,34] is particularly relevant to the discussion of the present results.”
• Atomic-scale grain boundary engineering to overcome hot-cracking in additively-manufactured superalloys (2019, result): “Hot cracks were found to systematically propagate along high angle grain boundaries (HAGBs) while low angle grain boundaries (LAGBs) were not susceptible to hot cracking, similarly to what was reported in the welding literature [19].”
