ABSTRACT
It is shown that temperature-dependent resistivity measurements of compacted and sintered powders allow for extracting independent information on sample density on the one hand and sintering-induced changes of grain-to-grain contacts on the other hand. The temperature gradient of the resistivity as a function of sample density follows (semi-) universal laws derived from percolation theory.

    Two different types of Ti-6AI-4V has been employed which are pre-alloyed and mixed powders. Mixed Ti-6AI-4V powder contains the appropriate combination of commercially pure titanum powder and 60% AI-40% V master alloy. Both powders were mixed with a thermoplastic binder, injected to form tensile...
