摘要： A method of making a ductile iron article is disclosed. The method includes providing a ductile iron article preform. The method also includes deforming the ductile iron article preform by hot-working to provide a hot-worked portion of the article. The method further includes cooling the article to an austempering temperature. Still further, the method includes austempering the ductile iron article preform for a predetermined time sufficient to provide an austempered article preform comprising an austempered microstructure, wherein the austempered microstructure of the hot-worked portion is different than in other portions of the article. A ductile iron wind turbine shaft is also disclosed. The ductile iron wind turbine shaft has an austempered microstructure comprising an ausferrite matrix and a plurality of graphite nodules. The austempered microstructure has a deformed portion, the deformed portion has a microstructure that is different than the microstructure of the other portion of the shaft.

摘要： A screw compressor of which a female rotor is driven by a motor, and of which a male rotor is driven by the female rotor. The male or female rotor is composed of a member which is made of cast iron and is subjected to surface hardening treatment or heat treatment including quenching. The surface hardening treatment may include sulphonitriding or nitiriding treatment. In the case of subjecting the cast iron to the heat treatment, austemper treatment is applied.

摘要： A scroll compressor includes scroll members that are made of austempered grey iron in whole or in part. The austempering process can increases fatigue strength and toughness of a grey iron while maintaining its good machinability and vibration damping characteristics. Use of austempered grey iron scroll members allows the scroll compressor to improve its capacity, efficiency, and durability.
