Study On Nanohardness Of Phases Occurring In ZnAl22Cu3 And ZnAl40Cu3 Alloys

Abstract: Zn-Al alloys are mainly used due to their high tribological and damping properties. A very important issue is determination of the hardness of the phases present in the Zn-Al-Cu alloys. Unfortunately, in literature there is lack of studies on the hardness of the phases present in the alloys Zn-Al-Cu. The aim of this research was to determine the hardness of the phases present in the ZnAl22Cu3Si and ZnAl40Cu3Si alloys. The scope of the research included examination of the structure, chemical composition of sele… Show more

“…With the increase of soaking time occurs (probably as a result of the diffusion) the further disintegration of the zinc-rich phase (dendrites) that goes to the eutectoid mixture and the complete disappearance of fine precipitates rich in Al visible earlier on the border of dendrites. Soaking at a temperature of 185°C leads to a partial loss of dendrites rich in zinc and copper [9][10][11]. Soaking of the ZnAl22Cu3 alloy at 385°C during 10 h increase in both hardness and in strength of the alloy.…”
