Phase assemblage	523.15	liquid + V2Sn3 alloy: V 0.2	experimental	[1] Chen 2008	p. 2 report	Figure 1 shows a BEI micrograph of alloy #1 (Sn-20.0at.%V) annealed at 250°C for 6 months. Two different phase regions are observed. The composition of the bright phase is Sn-0.1at.%V while that of the dark phase is Sn-33.7at.%V.
Phase assemblage	873.15	V3Sn + V alloy: V 0.85	experimental	[1] Chen 2008	p. 3 report	Figure 5 shows the BEI micrograph of alloy #6 (Sn-85.0at.%V) annealed at 600°C for 9 months. Two phases are observed. The composition of the bright phase is Sn-78.0at.%V while that of the dark phase is Sn-87.7at.%V; these are the V3Sn phase and V phase, respectively.
