Heat treating of a lamellar eutectic alloy (gamma/gamma prime + delta) [PDF]
Eutectic superalloys are being developed at several laboratories for application as aircraft gas turbine airfoils. One such alloy was subjected to several heat treatments to determine if its mechanical properties could be improved.
