Slip Lines in a Precipitation-Hardened Nickel-Base Alloy

Source

Many of the favorable high-temperature properties of the nickel-base heat-resistant alloys are well known to be due to an age-hardening process involving the precipitation of a fine dispersion of submicroscopic particles of the intermetallic γ' phase throughout the matrix of these alloys during aging and service at high temperatures. A number of papers have been published in recent years describing investigations of these alloys; however, it does not appear possible to understand completely the relationships between the microstructures and mechanical properties of these alloys because of a lack of information concerning the extent to which they γ' particles are coherent with the matrix at different stages in the aging process.
