In previous chapters we analyzed data from so-called one-way experimental designs, in which subjects were randomly assigned to groups that di↵ered on a single treatment or grouping variable. In this chapter we will analyze data from factorial experiments. Factorial experiments contain two or more experimental variables. In a completely crossed factorial experiment, each level of every variable ...

The Ni-based Hastelloy X (HX) superalloy is widely used in aero-engine components because of its exceptional high-temperature strength and oxidation resistance. Given the complex structure such parts, additive manufacturing (AM) technologies as laser powder bed fusion (LPBF) are employed to manufacture these components. HX alloy suffers from crack susceptibility during LPBF process, however. In...
