Contribution of the Strain Rate to the Generation of Residual Stresses During Deep Rolling and Machine Hammer Peening

Deep rolling and machine hammer peening are widely applied mechanical surface treatments for improving the fatigue performance of high-strength materials by introducing compressive residual stresses and modifying the near-surface material state. Despite their industrial relevance...

Gaussian process regression for optimizing L-DED processing parameters in AlSi10Mg additive manufacturing

Abstract This work presents an experimental workflow coupled with statistical tools to optimize L-DED processing parameters to build defect-free AlSi10Mg multilayer parts. Experimental steps included the quantitative evaluation of single beads, single layers, and multilayers to d...
