Abstract
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.
