Abstract:
Carpenter AerMet\sR 100 alloy is a nominally 0.23% C, 13.4%, Co, 3.1% Cr, 11.1% Ni, 1.2% Mo and balance Fe proprietary alloy designed for aerospace structural applications requiring a combination of high strength, high fracture toughness and good resistance to stress corrosion cracking. AerMet\sR 100 alloy was designed to be a candidate to replace 300M in the Navy's carrier based aircraft but it is now being evaluated for other applications where its nominal 285 ksi (1965 MPa) U.T.S., 115 ksi in. (126 MPa m) K\di\dc and 35 ksi in. (38 MPa m) K\di\ds\dc\dc in a 3.5% NaCl solution can be utilized. This paper presents AerMet\sR 100 alloy and discusses its typical properties after the recommended 1625\mDF (885\mDC), 1h solution treatment 900\mDF (482\mDC), 5 hour age. AerMet\sR 100 alloy is then compared with AF1410, marage 250, 300M, H11, HyTuf and 4340. Finally, aging curves for AerMet\sR 100 alloy aged for 5 hours between 200 and 950\mDF (93 and 510\mDC) are presented and the effects of aging treatments on mechanical properties are discussed
