The February issue of Materials Evaluation includes a feature paper on interpreting magnetic particle testing indications for gas turbine components. Technical papers highlight innovations such as statistical quality control methods for industrial X-ray computed tomography and advancements in detecting corrosion thinning in aluminum-steel structures using pulse eddy current technology. The issue also covers industry trends, including AI’s role in NDT, ISO 16823:2025, and ethical considerations on the use of ASNT’s logos. Additionally, it provides updates on ASNT’s strategic initiatives, industry news, new products, and global section activities.

Thermal and infrared testing is a crucial NDT method that’s well suited to many inspection challenges, but it’s a bit less well-known than some NDT methods. Last year, ASNT published the fourth edition of the Nondestructive Testing Handbook: Thermal and Infrared Testing, the largest and most complete handbook ever published by ASNT. We're joined by the technical editor for this new edition, Dr. Xavier Maldague, to give our listeners a primer on thermal and infrared testing. We spoke about the advancements that have been made in infrared testing and its application in many industries within NDT, as well as the key updates to the new handbook.
