The phase diagram for pure ${\mathrm{CO}}_2$ is depicted below: How many degrees of freedom exist at the orange point? 2 1 0 3 Please refer to the general A-B phase diagram depicting cooling at four possible fixed compositions (1-4) and four possible resulting microstructures (A-D) Upon cooling composition 2, the precipitated phase along the grain boundaries in microstructure $B$ will be what? beta alpha alpha + beta gamma
