Abstract

A precision casting of high pressure turbine blades and vanes consisting entirely of an oriented single grain of nickel-based superalloys has been introduced in most advanced aircraft engines due to their superior high temperature strength. This paper presents a description of the casting process for single crystal components and the evaluation of high temperature properties for a newly developed alloy TMS26 in comparison with the existing alloys. Major outcomes are summarized as follows;<BR>(1) Selecting the most adequate casting procedure and parameters, high quality single crystal blades in which their longitudinal orientation divergence from <100> was less than 10 degree were consistently procedured from TMS26 and CMSX-2 (an existing alloy) with a yield in excess of 90%.<BR>(2)Mechanical properties (tensile, creep and low cycle fatigue strength) and several physical properties of TMS26 were found to be generally superior to those of existing commercial alloys.
