Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
92 words
A METHOD OF PRODUCING A BERYLLIUM SHEET HAVING THREE DIMENSIONAL DUCTILITY WHICH COMPRISES CONFINING BERYLLIUM POWER WITHIN A DEFORMABLE CONTAINER, PRESSING SAID CONTAINER TO FORM A BILLET IN WHICH THE POWDER IS COMPOSED TO AT LEAST ABOUT 50% THEORETICAL DENSITY, HEATING SAID BILLET TO A TEMPERATURE BELOW THE MELTING POINT OF BERYLLIUM, UPSETTING SAID BILLET AT A TEMPERATURE IN THE RANGE 500-2100*F. AND AT A PRESSURE SUFFICIENT TO EFFECT A REDUCTION IN AREA OF SAID BILLET IN THE RANGE 3:1 TO 30:1 AND THEREAFTER REMOVING THE THUS FORMED SHEET FROM SAID CONTAINER.
