A NEW DISCOVERY... One of the recent achievements at JPL in the field of high temperature materials came as a result of careful X-ray diffraction studies of high purity alloys especially prepared at the Laboratory. A previously unknown compound was discovered in the titanium-aluminum alloy system, probably accounting for the low ductility observed in certain of these alloys.

To provide the new kinds of materials required for the unusual requirements of rockets, missiles, a n d nuclear propulsion, the Laboratory is engaged in research on materials suitable for high temperature uses and having high strength with minimum weight. This includes work in metallurgy, ceramics, solid state physics, a n d chemical thermodynamics. We are now examining t h e mechanical behavior of metals and ceramics near their melting points, phase diagrams and properties of alloys, diffusion in solids, kinetics of phase formation, crystal structures, and crystal imperfections. Thermodynamic studies of alloys and of high temperature materials are in progress in relation to phase equilibria and to corrosion resistance. T h e work in materials has companion efforts, comparable in scope, related to liquid and solid propellants, and to nuclear propulsion. Additional openings are available for qualified scientists. If the challenge of n e w problems i n research interests you, please write us outlining your education and experience.
