An investigation into the variation in porosity of a direct metal laser sintered artifact manufactured with the EOSINT M250 machine system using direct metal 20 powder
Olwagen, A.; Markgraaff, J. (RAPDASA, 2014)Direct Metal Laser Sintering (DMLS) is a rapid prototyping technique that allows for direct and rapid manufacturing of complex components. DMLS is however an intricate process and the quality of the final product is ... -
Optimization of counting time using count statistics on a diffraction beamline
Marais, D.; Venter, A.M.; Markgraaff, J. (Elsevier, 2016)The feasibility of an alternative data acquisition strategy to improve the efficiency of beam time usage with neutron strain scanner instruments is demonstrated. By performing strain measurements against set statistical ... -
Sample positioning in neutron diffraction experiments using a multi-material fiducial marker
Marais, D.; Venter, A.M.; Markgraaff, J.; James, J. (Elsevier, 2017)An alternative sample positioning method is reported for use in conjunction with sample positioning and experiment planning software systems deployed on some neutron diffraction strain scanners. In this approach, the ... -
Synthesis of cesium, sodium and nitrogen derived titanates using the Pechini sol-gel method
Mastoroudes, Bruce C.; Markgraaff, Johan; Wagener, Jacobus B.; Olivier, Ezra J. (Elsevier, 2020)Cesium and sodium titanates with the respective stoichiometries of CsxTi2-x/4□x/4O4 (x ≈ 0.7) and Na2Ti6O13 was synthesized by making use of the Pechini sol-gel method. Direct intercalation of hydrazine hydrate in cesium ...
