Definitions
- the powder mixture was dried and then 250 g of it were filled into a rubber tube with an inner diameter of 20 mm and pressed isostatically at a pressure of 3000 bar to a cylinder with an 18 mm diameter and a height of 240 mm.
- the green body was reduced in a hydrogen stream at a temperature of 930 ° C. for 1 Y2 h and presintered and then sintered in a stream of argon at a temperature of 960 ° C. for 18 h.
- the hammered down to 8 mm diameter rod was finally subjected to a final annealing in an argon stream for 15 minutes at a temperature of 920 0 C and then immediately quenched in water.
- the test showed a density of 99, 3 - 99.7% of the theoretical value for the matrix.
