ABSTRACT: The Selective Laser Melting (SLM) of metallic powders, especially of high-strength nickel
based alloys, allows for the manufacturing of aerospace components of high shape complexity and load capacity.
However, due to high temperature gradients, induced during laser processing, the structural properties and
geometrical accuracy of components can be affected. ...
