Abstract
Production and structural investigations of Cu-based FeCr reinforced composite were performed by using mechanical alloying, optical microscope, scanning electron microscope, X-ray diffraction and hardness test. The increment in FeCr addition caused the increment in the cold deformation rate. This situation resulted in breakage of the powder particles throughout mechanical alloying.
Thus, the grain dimension of the FeCr powders decreased and the Fe wt.% in the CuCr powders advanced. The collision force between the Cu-Cr powder and the grinding ball weakened with the increase of FeCr concentration and resulted as higher reinforcement size. After mechanical milling, FeCr grains decreased in size more than copper grains due to the ductility of copper grains. The smaller crystals occurred after grinding, and increased the grain boundary zone for further spread of Cr into the Cu. Despite the high sintering process, the high sintering temperature improved the compactness of the alloys, but caused coarsening of the nanoparticles. The mechanical alloying time, reinforcement wt.% and sinter temperature were effective on the micro-hardness of the microstructure.
Kurzfassung
Für die Herstellung und Gefügeuntersuchungen eines Cu-basierten und FeCr-verstärkten Verbundwerkstoffs wurden mechanisches Legieren, Lichtmikroskopie, Rasterelektronenmikroskopie, Röntgenbeugung und Härteprüfungen eingesetzt. Eine Erhöhung der FeCr-Zugabe führte zu einem Anstieg des Kaltverformungsgrads, was wiederum das Aufbrechen der Pulverpartikel während des mechanischen Legierens zur Folge hatte.
Somit nahm die Korngröße der FeCr-Partikel ab und der Gewichtsanteil an Fe in den CuCr-Pulvern stieg an. Die Stoßkräfte zwischen dem CuCr-Pulver und des Mahlkörpers nahm mit dem Anstieg der FeCr-Konzentration ab und führte zu einer Vergröberung der Verstärkungspartikel. Aufgrund der Duktilität der Kupferkörner nahm deren Größe durch das mechanische Mahlen weniger stark ab als die Größe der FeCr-Körner. Nach dem Mahlvorgang waren kleinere Kristalle und größere Korngrenzbereiche zu beobachten, sodass sich Cr weiter in Cu verteilen konnte. Zwar wurde durch die hohe Sintertemperatur die Kompaktheit der Legierungen verbessert, es kam jedoch auch zu einer Vergröberung der Nanopartikel. Die Dauer des mechanischen Legierungsvorgangs, der Gewichtsanteil der Verstärkungsphase sowie die Sintertemperatur wirken sich auf die Mikrohärte des Gefüges aus.
