36. Fatigue Performance of Additive Manufactured Ti6Al4V in Aerospace Applications
Sammanfattning : Additive Manufacturing (AM) for metals includes is a group of production methodst hat use a layer-by-layer approach to directly manufacture final parts. In recent years, the production rate and material quality of additive manufactured materials have improved rapidly which has gained increased interest from the industry to use AM not only for prototyping, but for serial production.

37. Microstructure Modelling of Additive Manufacturing of Alloy 718
Sammanfattning : In recent years, additive manufacturing (AM) of Alloy 718 has received increasing interest in the field of manufacturing engineering owing to its attractive features compared to those of conventional manufacturing methods. The ability to produce complicated geometries, low cost of retooling, and control of the microstructure are some of the advantages of the AM process over traditional manufacturing methods. LÄS MER
38. Mechanical Properties, Microstructures and Defects of Tool Steels Fabricated by Additive Manufacturing
Sammanfattning : Additive Manufacturing (AM) has been gaining significant interest in the manufacturing of metallic materials in the recent years. From a techno-commercial standpoint, tooling is one of the areas with low production volumes but very high demands on part performance and complexity in design, all of which are characteristic for metal AM.

39. Characterization of Fe-W alloys electrodeposited from environmentally friendly electrolyte
Sammanfattning : This work focuses on Fe-W and Fe-W/Al2O3 coatings electrodeposited from an environmentally friendly electrolyte: minimally invasive, thermodynamically stable, and without toxic compounds. Such coatings aim to be applied for protective applications and as a sustainable alternative to hard chromium coatings. LÄS MER
40. Effect of Stress Relief Annealing: Part Distortion, Mechanical Properties, and Microstructure of Additively Manufactured Austenitic Stainless Steel
Sammanfattning : Additive manufacturing (AM) processes may introduce large residual stresses in the as-built part, in particular the laser powder bed fusion process (L-PBF). The residual stress state is an inherent consequence of the heterogeneous heating and subsequent cooling during the process. LÄS MER
