Quite recently, Carpenter Technology Corporation developed and patented an ultrahigh-strength martensitic steel, named AerMet 100, which is stronger but has lower fracture toughness than AF1410. As the material itself is a recent development, the published studies on it are quite limited and they primarily investigated the mechanical properties after isochromal aging for only about 5 hours. In another study by these authors, this alloy was tested and analyzed in terms of the secondary hardening reaction in tempering at several different temperatures. In this work, the growth and coarsening behavior of the M{sub 2}C phase mainly at 482 C will be explored along with measurements of lattice constants and orientations.
