The Materials Technology Institute (MTI) has published the Atlas of Microstructures, providing much-needed data on the microstructural changes that occur in HP-modified, HPMA, and 35Cr/45Ni cast alloy reformer tubes upon long-term aging. The MTI-funded study fills an information void, picking up where a 1975 Battelle Columbus Laboratories report left off, covering the newer alloys used in industry today. In addition to documenting and illustrating changes that can occur with increased aging time and temperature, the Atlas of Microstructures provides identification and chemical composition of precipitated phases and includes diagrams characterizing the kinetics of phase transformation. It’s an in-depth resource that will prove beneficial to companies ranging from cast alloy producers and end users to external laboratories and researchers, according to co-author John Hoffman of Air Products and Chemicals. The Atlas of Microstructures is currently available to MTI member companies only. This hardbound full-color publication will be available to the public this fall for USD 1295 plus shipping and handling at https://www.mtiproducts.org/.
