Materials for A-USC Coal Power Plants – U.S. Department of Energy (DOE) and Ohio Funded Project
• During 1st 60 years of the 20th century, steam turbine temperatures rose from 250°C to 650°C – Thermal efficiency rose
from 4% to 40% (HHV) • Eddystone experienced
several materials issues – Derated from 650°C to
615°C • No improvements for 50
years!

News on A-USC Materials Development (hot off the press)
• In April 2011, at their works in Houston, Wyman-Gordon successfully extruded a ∼7.2-tonne ingot of Inconel 740 into a pipe section 0.38-m OD, 10.5-m long with 0.0.076-m wall thickness
• Tests are in progress to determine the properties on the extruded material
