INJECTION MOLDED TUNGSTEN HEAVY ALLOY①
Trans. Nonferrous Met. Soc. China Dec. 1998 Vol. 8 №.4,-0001,():
97W-2Ni-1Fe heavy alloy feedstocks with different powder loadings were prepared for injec-tion molding. The rheological behavior of these feedstocks was studied. The mechanical properties of as-sintered parts and the shrinkage during sintering were measured. The results showed that the rheological be-havior of these feedstocks could be described as pseudoplastic fluid. The mechanical properties of the injection molded alloy are superior to those of alloy prepared by conventional press/ sinter process. There is an optimal powder loading 47% (volume fraction) with the best mechanical properties. The shrinkage during sintering is isotropical and the tolerances of products are small.
