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

This paper describes a novel method for determining the specific action to melt the metals, and reports the values for action to melt that measure for several elements and three alloys: aluminum 2024, aluminum 6061, and C27400 brass. We electrically

A comprehensive approach is presented to perform model-based inversion of crack characteristics using bolt hole eddy current (BHEC) techniques. Data was acquired for a wide range of crack sizes and shapes, including mid-bore, corner and through-thick

Studies were conducted in Oklahoma and Arkansas to evaluate the tolerance of nine advanced cowpea breeding lines and one cultivar treated PRE with halosulfuron at 1× (0.054 kg ha−1) and 2× (0.107 kg ha−1) rates. The breeding lines, developed by

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

The Institute for Advanced Technology has been conducting experiments on plasma-armature railguns for the past several years. To control the damage mechanisms associated with this class of railgun, an electrothermal (ET) launcher preinjects the proje

In solid-armature railguns, hypervelocity gouging damage can significantly limit the useful life of rails. Most solutions to this problem have involved the use of hard rail materials, which tend to be poor electrical conductors. However, it has also

A large-caliber railgun was developed to demonstrate the supersonic launch of 120-mm projectiles. A trade study that evaluated over 70 different railgun configurations and geometries resulted in the selection of a high-inductance-gradient multiturn c
