Abstract
After careful review of literature, the La–Zn phase diagram is reinvestigated by X-ray diffraction, scanning electron microscopy, microprobe analysis and differential thermal analyses. A more accurate description of the diagram is proposed. Among the eight intermetallic compounds, LaZn, LaZn2 and La2Zn17 melt congruently whereas LaZn4, LaZn5, La3Zn22, LaZn11 and LaZn13 decompose peritectically. The diagram includes four eutectic and one metatectic invariant reactions.
► Twelve La–Zn alloys were synthesised. ► Metallographics analyses are performed on them. ► The temperature of transition is measured by differential thermal analysis ► The temperature of invariant reaction is determined. ► The phase diagram is redrawn.
