Abstract:

Rheological properties of polycrystalline iridium of I 99.9 grade are investigated in order to construct the dependence of deformation resistance on studied factors (strain ratio, rate, and temperature). The tests of cylindrical samples made of iridium are performed using a cam plastometer in temperature range t = 900-1400A degrees C at strain rates xi = 0.2 and 20 s(-1), as well as at t = 800-1400A degrees C and xi = 2 s(-1) using the upsetting method at a strain rate up to 0.8. The results of investigations can be used to develop the pressure treatment of iridium wares at large plastic strains and in a broad range of thermomechanical parameters.
