Microstructure and susceptibility to hot tearing of K424 nickel-based superalloys for turbocharger turbine wheels

Hot tearing tends to occur when K424 superalloy is used for a turbocharger turbine wheel. To solve this problem,the alloy characteristics of K424 and K418 superalloys and the factors impacting the susceptibility to hot tearing were studied by microstructure observations and casting simulations. The...
