Thermal stability of eutectic and off-eutectic Ag-Cu, Cd-Zn and Al-ζ(AlAg) alloys - Cantor, B.; Chadwick, G.A. (Elsevier)
Conventional optical metallography has been used to investigate the effect of high temperature exposure on the microstructures of directionally solidified Ag-Cu, Cd-Zn, and Al-ζ(AlAg) eutectics, and as-cast hypo- and hyper-eutectic alloys in the same systems. The lamellar eutectic alloys coarsen by a mechanism similar to that described by Graham and Kraft, with lamellae receding from grain boundaries and lamellar faults. However, the coarsening behaviour of the cross-hatched blade structure in Ag-Cu eutectic is less homogeneous. The effect of primary dendrites in hypo- and hyper-eutectics is to accelerate the rate of coarsening.
