Figure 6

Schematic of the formation of β allotriomorphs on the grain boundaries (GB) with the contact angle θ indicated and two possible loci of the particles with incipient heterogeneous β crystallization. Potential diffusion paths via lattice diffusion (Jl) and grain boundary diffusion are also depicted.
