Ultrasonic inspection was used to detect regions of recrystallization (RX) within a single crystal of Ni. RX can produce polycrystalline regions within single-crystal (SX) materials. Because RX regions act as initiator sites for failure by fatigue-cr

Hypervelocity gouging occurs in high speed sliding systems such as rocket sled test tracks, light gas guns, and electromagnetic railguns. Gouging takes the form of teardrop-shaped craters on the rail surface, and occurs above a threshold speed which

Because the 5000-series aluminum alloys are not heat treatable, controlling their microstructures during deformation processing to achieve fine grain sizes is particularly important. Recrystallization during or immediately following hot deformation p

The microstructure of a vacuum arc remelted (VAR) nickel alloy 718 ingot was characterized using macro photography and studied with quantitative image analysis techniques. Microstructure quantification was used to produce information that may aid the

Material ejected from aluminum armatures at the rail-armature interface has been identified as a mechanism that degrades both rails and insulators in a railgun, significantly reducing the bore lifetime. With the goal of controlling the onset of armat

It is hypothesized that damage to G10 railgun insulators occurs when a very concentrated stream of molten aluminum, which is ejected out of the armature-rail interface, impacts the insulators at 90° angle and acts as a cutting tool that erodes away

One of the difficulties associated with electromagnetic launch is the lack of diagnostic tools capable of surviving the in-bore environment. In railguns, the principal diagnostics are current and voltage measurements, in addition to magnetic field (B
