Lockalloy Be-38Al Material Characterization, 1976 Year-End Report,
Abstract
Lockalloy, Be-38Al, is a beryllium-aluminum composite material originally developed by LMSC. The potential use of Lockalloy as a structural material is emphasized for applications on Hypersonic Flight Vehicles or other installations requiring high stiffness to weight ratios, high heat conductivity and/or high specific heat. This year-end report documents the results to date of a testing program to further establish the characteristics of Lockalloy material. The testing was performed by Advanced Design Projects (ADP) personnel. These tests involved experimental and analytical studies conducted to obtain additional information regarding basic Be-38Al Lockalloy material properties and characteristics. The studies provide data regarding impact strength, resistance to stress corrosion, response to post-manufacturing thermal treatment, weldability, and inspectability. The accuracy of methods for determining the modulus of elasticity and predicting compression instability (column strength) were also verified. In addition, the behavior of this material in certain structural concepts, considered for the X-24C airplane was evaluated.
