Development of dispersion-strengthened Ni-Cr-ThO2 alloys for the space shuttle thermal protection system.
An improved manufacturing process has been developed for TD-NiCr that provides sheet of improved quality, better gage control, and reproducible properties. A standard manufacturing process has been developed for the alternate alloy, DS-NiCr, produced by pack-chromizing Ni-2ThO2 sheet. Extension of forming and joining technology for TD-NiCr is in process. Formability criteria are being established for basic sheet forming processes related to the manufacture of Shuttle TPS panels. They include brake forming, corrugation forming, joggling, dimpling, and beading. Joining processes applicable to TPS panels are being optimized with emphasis on establishment of joint efficiencies. Resistance spot welding (fusion and solid state), resistance seam welding, solid-state diffusion welding, and brazing are included in the joining programs. Development of improved manufacturing technology for TD-NiCr fasteners is also being accomplished. Mechanical and physical properties of TD-NiCr are being characterized to provide design-allowable data.

Occurrence of diopside and Cr-Zr-armalcolite on the moon.
Petrographic and electron-microprobe examination of the sample of 1 to 2 mm fines, Apollo 14166,6, has revealed a fragment with the unique lunar mineralogy of plagioclase, olivine, diopside, a Ti-Fe-Zr phase, and a trace of ilminite. The second occurrence of diopside is reported together with the third occurrence of a recently identified Ti-Fe-Zr phase. Microprobe analyses of the principal phases of the fragment studied are presented in a table. The relatively pure diopside analyses reported represent the most Mg-rich calcic pyroxene found in lunar material.
