Apstrakt

Istraženi su i objašnjeni problemi pri injekcionom brizganju različitih legura magnezijuma. Ispitivanja sprovedena sa legurama magnezijuma AZ91D, ZC63 i MRI230D su pokazala da pored poznatih uzroka, na poremećaj pri injekcionom brizganju mogu uticati i drugi faktori, kao što su kontaminacija granulata, neravnine i veličina finih čestica, eutektikumi sa niskom tačkom topljenja i vlakna koja se koriste za ojačavanje legura magnezijuma. Analizirani su uzroci faktora poremećaja koji nastaju i razvijena su rešenja za njihovo otklanjanje i izbegavanje.
