Abstract: | The occurrence of a significant amount of age hardening, due to the precipitation of the γ′ phase, has been demonstrated in
the nickel-copper base alloy MONEL K 500. The microstructure of the precipitation-hardened and deformed alloy has been examined
in peak-aged underaged and overaged conditions. An attempt has been made to compare the observed increments in strength in
these three aged conditions to those predicted on the basis of relevant theoretical models. |
