2. 1. Stainless steels fabricated by laser melting : Scaled-down structural hierarchies and microstructural heterogeneities

   Author : Kamran Saeidi; Zhijian Shen; Xiaoxu Huang; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Selective laser melting; Stainless steel; Structural hierarchies; Microstructure heterogeneity; Mechanical properties; Materials Chemistry; materialkemi;

   Abstract : Additive manufacturing is revolutionizing the way of production and use of materials. The clear tendency for shifting from mass production to individual production of net-shape components has encouraged using selective laser melting (SLM) or electron beam melting (EBM). READ MORE

4. 2. Geometry Assurance of Laser Processed Metal Components

   Author : Vaishak Ramesh Sagar; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; selective laser melting; Geometry assurance; geometric variation; selective laser heat treatment; robust design;

   Abstract : The manufacturing industry largely contributes to the global economy. How-ever, with the growing complexity of customer demands, stringent environmental norms, and requirements for shorter product development lead times, the industry continues to seek alternatives to address these challenges.

   Abstract : The thesis focuses on exploring the sub-grain structure in stainless steel 316L prepared by additive manufacturing (AM). Two powder-bed based AM methods are involved: selective laser melting (SLM) and electron beam melting (EBM). READ MORE

6. 4. Additive metallurgy - Thermal influences on structure and properties of stainless steel 316L

   Author : Jon Olsén; Zhijian James Shen; Dongdong Gu; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Additive manufacturing; Selective laser melting; Electron beam melting; Hot isostatic pressing; Stainless steel; Microstructural heterogeneity; Materials Chemistry; materialkemi;

   Abstract : Additive manufacturing (AM) as a manufacturing process has, in recent years, become widely accepted as capable of manufacturing parts that will be used in end products. In this thesis, stainless steel grade 316L parts are manufactured using two different powder bed fusion techniques, selective laser melting (SLM) and electron beam melting (EBM). READ MORE

7. 5. Tailoring structure and morphology during additive manufacturing of metallic components

   Author : Jithin James Marattukalam; Björgvin Hjörvarsson; Ulf Jansson; Martin Sahlberg; Lars Nyborg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective laser melting; process parameters; scanning methodologies; AMLOYZR01; bulk metallic glass; 316L SS; grain orientation;

   Abstract : The work described in this thesis explores the use of laser process parameters to functionalize the material properties by the control of microstructure and optimization of morphology in components by selective laser melting. The microstructure in amorphous and crystalline metallic alloy systems is influenced by changing the laser power density and scanning strategies respectively. READ MORE
