Density of the as-cast (AC) alloys and area % of selected phases in the bulk of the as-cast and heat-treated (HT) alloys JZ4 and JZ5.

Alloy	Density (g/cm3)	Solid Solution (%)	A15 (%)
JZ4-AC	7.28 ± 0.01	-	19.8 ± 3.2
	7.27–7.29		17.3–23.4
JZ4-HT a	-	3.3 ± 0.5	12.2 ± 2.0
		2.7–3.6	10.9–14.5
JZ5-AC	6.91 ± 0.06	-	12.7 ± 1.1
	6.87–7.01		11.4–13.4
JZ5-HT a	-	2.3 ± 0.3	10.6 ± 0.3
		2.1–2.6	10.4–10.9

^a Some hafnia may be included in the measurement because the oxide exhibited the same contrast as the solid solution.
