Thesis (Master): Influence of Process Parameters and In-situ Heat Treatment on the Microstructure of Additively Manufactured Copper Alloys
Within the scope of this master thesis, the relationships between process control, microstructure and material properties of additively manufactured copper alloys are investigated. The samples are produced by Powder Bed Fusion Laser Beam (PBF-LB) with an Aconity Mini at the fem research institute and comprise the precipitation-curing copper alloys CuNiAl and CuNiSiCr. A special focus is on the systematic investigation of the influence of laser power, scanning speed and further process parameters as well as the targeted use of in-situ heat treatment effects during the construction process. For the newly developed alloy CuNiAl, suitable process parameters are first determined using statistical methods, for example design of experiments (DOE). Based on this, parameter studies are carried out to analyze the influence of process management on microstructure formation and material properties. The PBF-LB system is controlled by Autodesk Netfabb. The production of construction jobs and the parameterization of the manufacturing process are done with this software. First experiences in handling Autodesk Netfabb for process preparation of additive manufacturing processes are therefore desirable. The samples produced are subsequently characterized comprehensively microstructured. These include metallographic preparation and investigations by means of light microscopy, scanning electron microscopy (REM), EBSD, X-ray diffractometry (XRD) and hardness measurements for analyzing local curing effects. The aim is to quantify the effects of process parameters and thermal history on porosity, grain structure, precipitation formation and mechanical properties of copper alloys. The results of the work contribute to the basic understanding of the process microstructure property relationships of additively manufactured copper alloys and create a scientific basis for the optimization of industrial manufacturing processes. .
