 | | In the same manner, the coalescence temperature of dendrites across a grain boundary (intergranular coalescence temperature), Tcg, and within a grain (intragranular coalescence temperature), Tcd, have been evaluated, as shown in Figures 7a and 7b and Figures 8a and 8b, respectively. |
 | | Coalescence, or bridging of dendrite arms, is established when the liquid film between two adjacent dendrites or two grains is no more continuous (see Figure 7b and Figure 8b). |
 | | Indeed, coalescence is a key parameter for the understanding of the mechanical property of the mush and of the hot tearing phenomenon. |
