Abstract

In this paper,the cost,properties and castability of DD3single crystal alloy had been evaluated.The results show that DD3single crystal alloy has excellent mechanical properties equivalent to that of PWA1 480 single crystal alloy.The casting test exhibited the excellent single crystal castability of DD3.The single crystal turbine blades of DD3alloy can be produced at low cost.So DD3is an applicable single crystal superalloy for turbine blades in aeroengines.

Key words

superalloy / single crystal / turbine blades
