Structuras of the Eutectoid Zn-Al Alloy Obtained by Directed Solidification
MetadataShow full item record
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 of the eutectoid transformation, changed within the ranges of 0.6-4.6, respectively 1.2-6.4 oC/mm. The results of the dilatometric analyses and of microhardness on different crystalline areas are presented.
