Precipitation characteristics and strengthening mechanism in 8% Ni-6% Cr-Co-Mo maraging steels were investigated. The precipitates contributing to strengthening of the steel were spherical ones of about 200A in diameter and ribbon-like ones of about 100Å in width and 300-500Å in length. The both types of precipitates were identified with Fe2Mo Laves phase. In the steel, the addition of Co accelerated precipitation hardening by retarding recovery of dislocation during aging. The precipitation hardening of the steel can be explained in terms of Orowan's theory.
