Laser melting leads to a rapid solidification, individual melt lines are recognizable. Different heat treatment parameters result from different dissolution and precipitation behavior

Within the framework of the project, AlSi10Mg and 17-4PH specimens are produced by laser beam melting, heat-treated and finally analyzed by materials science.

The interactions between laser beam melting, heat treatment and resulting material properties are demonstrated by systematic experimental planning.

On the basis of this scientific approach, specific heat treatment rules for laser beam fused components are derived from AlSi10Mg and 17-4PH, which is a direct industrial benefit.
