Process Capability Indices With Student Mixture Models Applied to Aircraft Engines GD&T

Abstract Usually, the process capability indices (PCIs) Cp and Cpk are used to quantify the production quality of Geometric Dimensioning & Tolerancing (GD&T). For the most popular PCIs, a strong assumption about normality is required. Many…

L-PBF and DED processing of a Ni-based superalloy

Different additive manufacturing (AM) technologies such as L-PBF and DED do become really attractive for both repair and 3D part manufacturing. In particular, extensive work is in progress for the non-weldable nickel-based superalloys which tend to…

Revisiting the influence of the scanning speed on surface topography and microstructure of IN718 thin walls in directed energy deposition additive manufacturing

Controlling the mechanical properties of metallic parts produced by additive manufacturing remains challenging. The mechanical behavior of parts is mainly related to the microstructure, which depends on process parameters and manufacturing…
