In this work, the G-NiCu30Nb casting alloy, a variant of the Monel family of alloys with Nb and high Si content is, for the first time, processed via the laser powder bed fusion process (LPBF). Being novel to the LPBF processes, optimum LPBF parameters were determined, and hardness and tensile tests were performed in as-built conditions and after heat treatment at 1000 °C. Microstructures of the as-cast and the as-built condition were compared. Highly dense samples (99.8\% density) were achieved after varying hatch distance (80 µm and 140 µm) with scanning speed (550 mm/s-1500 mm/s). There was no significant difference in microhardness between varied hatch distance print sets. Microhardness of the as-built condition (247 HV0.2) exceeded the as-cast microhardness (179 HV0.2.). Tensile specimens built in vertical (V) and horizontal (H) orientations revealed degrees of anisotropy and were superior to conventionally reported figures. Post heat treatment increased ductility from 20\% to 31\% (V), as well as from 16\% to 25\% (H), while ultimate tensile strength (UTS) and yield strength (YS) were considerably reduced.}, language = {en} } @article{RamazaniLiMukherjeeetal.2013, author = {Ramazani, Ali and Li, Yang and Mukherjee, Krishnendu and Prahl, Ulrich and Bleck, Wolfgang and Abdurakhmanov, Aydemir and Schleser, Markus and Reisgen, Uwe}, title = {Microstructure evolution simulation in hot rolled DP600 steel during gas metal arc welding}, series = {Computational materials science}, volume = {Vol. 68}, journal = {Computational materials science}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1879-0801 (E-Book); 0927-0256 (Print)}, pages = {107 -- 116}, year = {2013}, language = {en} } @inproceedings{RaupachOrlowskyBuettneretal.2006, author = {Raupach, Michael and Orlowsky, Jeannette and B{\"u}ttner, T. and Dilthey, Ulrich and Schleser, Markus}, title = {Epoxy-impregnated textiles in concrete - load bearing capacity and durability}, series = {Textile reinforced concrete : proceedings of the 1.
