In additive manufacturing (AM), there are many potential benefits for cost savings, among them being • integration of many conventional components into a single AM build; • complex shapes and orientations; • product volume control (short runs for sustainment vs. longer runs for new production); and • limited post-build [...]
A turbocharger client of ours wanted to improve durability and reduce warranty costs on cast wheels made from a nickel superalloy with a radially-solidified (RS) microstructure. A significant portion of their previous field failures had been attributed to high cycle fatigue (HCF). […]
A couple of months ago, there was an anniversary that might not be very well-known: July 27, 1949. It is a date as momentous for air travel as it is for the advancement of the field of fatigue and fracture mechanics. On this date, the de Havilland Comet, the [...]

While touting the benefits of extensive laboratory testing, the fine print said that “…results of the testing have not been proven to predict clinical wear performance…” How true. Laboratory testing is rarely indicative of true [...]
