Solidification characteristics and hot tearing susceptibility of Ni-based superalloys for turbocharger turbine wheel

The solidification characteristics and the hot tearing susceptibility were investigated on two Ni-based superalloys for turbocharger turbine wheel, K418 and K419. The segregation behaviors of the alloying elements and the precipitation phases were also studied. The results show that the solidificati...
