Godkänd; 2012; Bibliografisk uppgift: High velocity compaction (HVC) is a production technique with capacity to significantly improve the mechanical properties of powder metallurgy parts. The powder material used in the experiments was a press-ready premix consisting of Distaloy AE, 0.5% graphite and 0.6% Kenolube. The compressive properties of cylindrical specimens made by HVC were measured using a split Hopkinson pressure bar (SHPB) and standard static testing machine. The experimental results, such as maximum stress, Young’s modulus and failure behavior, under uniaxial stress condition using SHPB were compared with those of static compressive tests. During dynamic compression, the failure behavior of specimens was also observed using a high speed video camera. Among specimens made by HVC, the effects of specimen density, 6.9, 7.2 and 7.4 g/cm3, on the compressive properties were examined. The results of the dynamic compressive tests show approximately a 20% higher maximum stress than the results of the corresponding static compressive tests.; 20130320 (gusgus)
