Summary A study has been made of the shrinkage characteristics of compacts obtained by pressing: 1) active powders of electrolytic origin, 2) powders thoroughly deactivated by high-temperature annealing, and 3) a mixture of equal amounts of the above two powders. It is shown that the observed shrinkage characteristics can be qualitatively explained by assuming that, in addition to the usual mechanism of deactivation operating during annealing, there is also a mechanism of activity loss resulting from defect migration from active to deactivated particles.Translated from Poroshkovaya Metallurgiya, No. 4 (64), pp. 18–21, April, 1968.  相似文献

Conclusions The isostructural intermediate -phases Fe7W5 and Co7W6 in the W—Fe—Co system form a continuous series of -solid solutions. In the 1640–1630°C range the L + (Fe7W6) peritectic equilibrium in this system changes to a similar L + (Co7W6) equilibrium, where is the tungsten-base boundary solution.In the W-Fe-Co-Ni polythermal tetrahedron in the 1470–1460°C range conversion of the L +(Fe7W6)+, peritectic equilibrium into the similar L + (Co7W6) + , where is the nickel-, -ironcobalt-base boundary solution, occurs.Upon completion of crystallization at 1400°C, the W-Fe-Co system alloys with 10–20% (Fe + Co) have a + phase composition, while the W-Fe-Co-Ni system alloys with 10–20% (Fe + Co + Ni) accordingly have + , + + or + . At temperatures below 1215°C in alloys rich in iron, FeW may be formed instead of -phase and therefore the alloys may have an + FeW, + + FeW, + + + FeW and + + FeW phase composition.Translated from Poroshkovaya Metallurgiya, No. 5(281), pp. 86–89, May, 1986.  相似文献
