Sulfur embrittlement on γ/γ′ interface of Ni-base single crystal superalloys

The impurity sulfur embrittlement on γ/γ′ interface of Ni-base single crystal superalloys has been investigated by first principles quantum mechanics DMol calculations. Using a local sum of vertical (∑BO v) and horizontal (∑BO h)Mayer bond orders, we proposed a new method to evaluate the competition...
