Advanced Materials for Radiation Hardening

Understanding that saving weight without sacrificing performance on a vehicle is important, the objective of this program is to demonstrate Advanced lightweight materials (1.4-2.2 gm/cm3) materials that can have Radiation Hardened capability. These applications will have specific requirements of high thermal conductivity, low thermal conductivity, radiation resistance, Modulus, tensile strength, ductility, and machinability, to name a few. This Phase I program is designed to achieve this success without sacrificing performance and reducing overall costs for potential MDA components. Specific data for the various compositions of each engineered system will be generated and compared to MDA requirements under the Phase I. Both coupon level and Radiation testing and characterization will occur in Phase I. APS has assembled an expert team in the materials and characterization fields and has been provided overwhelming support to achieve a successful Phase I. The Phase II program will further define replacement parts and additional requirements for these unique materials.
