Several preliminary static capsule tests were made at 2000 deg F using Hastelloy X as capsule material and He as internal atmosphere. The results for the Nb--Al/sub 2/O/sub 3/ compatibility test run for 350 hr revealed a hardness increase and a small surface layer formed on the Nb tab. Results for the Nb--K compatibility test run for 25 hr indicated a slight weight loss in the wrought Nb tab amounting to 0.83 and 1.43 mg/cm/sup 2/ day, and metallographic examination revealed no discernible attack on either Nb or Hastelloy X by K. Dynamic capsule and loop equipment for future compatibility studies and machanical property tests to be used are described. (D.L.C.)
