Resesrches on the Production of Copper-Based Composites by Powder Metallurgy Methods
(Universitatea "Dunărea de Jos" din Galați, 2014)The article presents how to obtain copper matrix composite with alloy particles of NiCrBFeAl as complementary phase. The samples were obtained by powder metallurgy methods using different percentages of the additional ... -
Structuras of the Eutectoid Zn-Al Alloy Obtained by Directed Solidification
(Universitatea "Dunărea de Jos" din Galați, 2014)This work analyses the structure of the eutectoid Zn-Al based alloy directionally solidified, with cooling rates ranging between 8.5-0.4 oC/sec. During cooling, the temperature gradient in the liquidus zone, respectively ...
