Journal ArticleDOI
Laser additive manufacturing of hot work tool steel by means of a starting powder containing partly spherical pure elements and ferroalloys
A. Taruttis,C. Hardes,Arne Röttger,Volker Uhlenwinkel,Abootorab Baqerzadeh Chehreh,Werner Theisen,Frank Walther,Hans-Werner Zoch +7 more
TL;DR: In this article, an alternative alloying strategy for hot-work tool steel powder, provided for laser powder bed fusion (L-PBF), is proposed. But the results of this approach are limited to the case of high-performance materials such as martensitic hardenable tool steels.
Journal ArticleDOI
Additive manufacturing of a carbon-martensitic hot-work tool steel using a powder mixture – Microstructure, post-processing, mechanical properties
Felix Großwendt,Arne Röttger,Anna Luise Strauch,Abootorab Baqerzadeh Chehreh,Volker Uhlenwinkel,Rainer Fechte-Heinen,Frank Walther,Sebastian Weber,Werner Theisen +8 more
TL;DR: In this paper, the microstructure formation of a hot-work tool steel using laser-based powder bed fusion of metals (PBF-LB/M) was examined using electron microscopy.
Journal ArticleDOI
Effect of Corrosion and Surface Finishing on Fatigue Behavior of Friction Stir Welded EN AW-5754 Aluminum Alloy Using Various Tool Configurations.
TL;DR: It was found that material removal from the weld and root surfaces of the specimens, increased the fracture stresses of conventional and dual-rotational FSW from 204 to 229 MPa and 196 to 226 MPa, respectively, but this increase could not be detected in stationary shoulder FSW.
Journal ArticleDOI
Microstructural Characteristics and Residual Stresses in Arc-Sprayed Cermet Coatings Using Different Carbide Grain Size Fractions
TL;DR: In this article, a study on the residual stress field in coatings formed by an arc spraying process for different electric parameter settings has been carried out using different wire configurations, where iron-based cored wires with different grain-sized tungsten carbides as filler material were used as feedstock.
Journal ArticleDOI
Quality over Quantity: How Different Dispersion Qualities of Minute Amounts of Nano-Additives Affect Material Properties in Powder Bed Fusion of Polyamide 12
Alexander Sommereyns,Stan Gann,Jochen Schmidt,Abootorab Baqerzadeh Chehreh,Arne Lüddecke,Frank Walther,Bilal Gökce,Stephan Barcikowski,Michael Schmidt +8 more
TL;DR: In this paper, the impact of the quantity and dispersion quality of carbon nanoparticles deposited on polyamide 12 particles is investigated using tensile and cubic specimens manufactured under the same process conditions.
