NETL Researchers Coauthor Article for Journal’s 50-Year Anniversary Issue

Three NETL researchers coauthored an invited article on nickel-based superalloys for the 50th anniversary issue of the prestigious journal Metallurgical and Materials Transactions (MMT) A. The paper, titled “Solving Recent Challenges for Wrought Ni-Base Superalloys,” discussed the status of technology, design and manufacture of advanced superalloys required for fossil energy and aerospace applications. Martin Detrois, Paul Jablonski and Jeffery Hawk, all based at NETL’s Albany site, contributed to the article by conducting a review of work to understand the suitability of candidate alloys for multiple applications in advanced-ultra supercritical (AUSC) coal-fired power plants, which will burn hotter and more efficiently than current plants to provide more power with fewer emissions.

In the article, the NETL researchers noted that potential AUSC superalloys must have high-temperature strength; long-term creep strength, which is the ability of the material to resist deforming under heat and pressure; phase stability, which contributes to extended service life; oxidation resistance and weldability. However, the candidate alloys must balance these critical attributes with an ease of manufacturing that is critical for industry adoption. The article on nickel-based superalloys was one of five alloy articles making up the special 50th anniversary collection of MMT A.

NETL is a U.S. Department of Energy national laboratory that produces technological solutions for America’s energy challenges. From developing creative innovations and efficient energy systems that make coal more competitive, to advancing technologies that enhance oil and natural gas extraction and transmission processes, NETL research is providing breakthroughs and discoveries that support domestic energy initiatives, stimulate a growing economy, and improve the health, safety, and security of all Americans. Highly skilled men and women at NETL’s sites in Albany, Oregon; Anchorage, Alaska; Houston, Texas; Morgantown, West Virginia; and Pittsburgh, Pennsylvania conduct a broad range of research activities that support DOE’s mission to advance the national, economic, and energy security of the United States.
