6. The absorption of laser light by rough metal surfaces
Sammanfattning : In Laser Material Processing of metals, an understanding of the fundamental absorption mechanisms plays a vital role in determining the optimum processing parameters and conditions. The absorptance, which is the fraction of the incident laser light which is absorbed, depends on a number of different parameters. LÄS MER
7. Spectral analysis in laser powder bed fusion
Sammanfattning : This thesis is about the investigation of the spectral interaction of electromagnetic radiation with metal powders. For this purpose, spectral data of powders for laser powder bed fusion processes are investigated in three papers using different techniques. LÄS MER
8. Aspects of material and heat transfer in drop- and powder-based laser additive manufacturing
Sammanfattning : Additive Manufacturing became a major research topic and part of industrial production in the past years. Numerous techniques now allow to build 3D structures with a wide choice of materials. When it comes to processing of metals, a laser beam is often used as a heat source to melt either a wire or powder. LÄS MER
9. Laser-induced recoil pressure on metal drops and powder particles
Sammanfattning : Additive Manufacturing became a major research topic and part of industrial production in the past years. Numerous techniques now allow to build 3D structures with a wide choice of materials. LÄS MER
10. Laser-induced phase transformations in microalloyed steels
Sammanfattning : The application of thermal cycles below melting temperature can induce solid-to-solid phase transformation in steels, which is the transition between different crystalline structures of the same compound. There are many types of crystalline structures in steels produced, depending on the characteristics of the applied thermal cycle. LÄS MER
