Room temperature mechanical swaging of metallic powders allows the flexible synthesis of fully consolidated, chemically reactive composite powder compacts that can retain nearly the full strength, toughness, density, and machinability of their bulk parent elements. By means of post-mortem soft-catch and recovery of fragmented…
Metallic alloys with superior mechanical properties at elevated temperatures remain in high demand for a variety of applications in aerospace, space, and energy industries. With a high melting temperature (>2400 degree Celsius) and desirable ductility, niobium is a potential candidate for extreme environments that…
This paper discusses an approach to improve the structural performance of the fabric back bumper in a Whipple shield design for space applications using a polymer spray coating, 3M Super 77 adhesive on the fabric layers. The use of a polymer coating protects the…
The Laser-Induced Particle Impact Test (LIPIT) has become a prevalent method for probing projectile, target, and synergistic projectile-target responses to high strain rate deformation on the microscale. LIPIT’s advantages over other microscale launching techniques include the ability to controllably launch a single microparticle and…
Planetary defense test mission by NASA have used the philosophy of Kinetic impactor in its DART (Double Asteroid Redirection Test) mission. The primary concept in these hypervelocity impact events lies in impacting an asteroid (target) with a spacecraft (projectile) such that ejecta produced from…
Magnesium alloys have received much attention because of their high specific strength as well as recent advances in manufacturing processes. They have been applied in light-weight consumer electronics such as laptops and smartphone, and are being considered for automobile and aerospace applications. However, magnesium…
