摘要： A thrust reverser system drive shaft assembly is provided that includes a first shaft and a barrel. The first shaft has an end section and comprises an age-hardenable martinsitic steel alloy material having fracture toughness, stress corrosion cracking resistance, and a tensile strength of at least about 285 ksi during an impact rotational speed of at least about 14,000 rpm. The barrel has a first end, a second end, and a channel formed therethrough. The first end has the first shaft end section disposed therein. The barrel comprises steel alloy material that is different than the first shaft material, has an elongation of at least about 12% in a hardened condition, and is compatible to be welded to the first shaft material.
