Abstract: In one aspect, cobalt-based alloys are described herein comprising composition and microstructure permitting a balance of hardness, toughness and wear resistance desirable for wood cutting applications. A cobalt-based alloy comprises a chromium rich carbide phase in an amount of 15-30 volume percent, a tungsten-rich phase in an amount of 9-15 volume percent and a balance of cobalt-rich solid solution matrix comprising nickel, chromium, vanadium and tungsten.
