Product DatasheetAerMet 100
General InformationAerMet 100 alloy is an alloy possessing high hardness and strength combined with exceptional ductility and toughness. The alloy is designed for components requiring high strength, high fracture toughness and exceptional resistance to stress corrosion cracking and fatigue.
Processing and AssemblyThe solution treatment temperature range is 885°C +/-14°C for 1 hour. The solution treatment temperature must be monitored by a thermocouple attached to the load. Water quenching is not recommended. Proper quenching practice is essential for AerMet 100 alloy. The alloy should be cooled from the solution treatment temperature to 66°C in 1 to 2 hours to develop optimum properties. Following cooling to room temperature, to obtain the full toughness capability AerMet 100 alloy should be cooled to - 73°C and held for 1 hour. The parts can then be air warmed. AerMet 100 alloy exhibits minimal size change during heat treatment; however, for some parts, mechanical straightening to compensate for distortion during heat treatment is appropriate. Prior to straightening, a low temperature stress relief at 177/204°C for 5 hours following the refrigeration operation will provide an optimal combination of ductility and yield strength for the mechanical straightening operation. The standard aging treatment for AerMet 100 alloy is 482°C +/-6°C for 5 hours. Parts made from AerMet 100 alloy should never be aged at a temperature below 468°C.
PrecautionsLike other carbon bearing high strength alloys, AerMet 100 alloy is subject to decarburization during hardening. Heat treatment should take place in a neutral atmosphere furnace, salt bath or vacuum.
