Abstract
1. The optimum compacting pressures for niobium and molybdenum are 4000–6000 daN/cm2. 2. The maximum compact density is secured under the following sintering conditions: a) for molybdenum: temperature 2173°K, isothermal holding for 4–5 h, environment-hydrogen; b) for niobium: temperature 2173°K, isothermal holding for 3–4 h, vacuum of 0.133 N/m2(l ·10−3mmHg). 3. Molybdenum and, particularly, niobium show little tendency to strength loss in the temperature range 293-1473°K.
