The Microstructural Impact on High Temperature Corrosion in DMV 617 mod under Coal-Fired Conditions

Nickel-based materials are applied in the next generation of advanced super critical coal power plants. This next generation shows a better efficiency by using a higher operating temperature of 700 °C compared to 600 °C in conventional coal power plants. However, new materials need to be developed for the power plant construction which can withstand this increased temperature under combustion gases. In this study, the new developed nickel-based alloy DMV 617 mod was investigated.
