A technology of hardening porous materials of titan powders has been elaborated. The
technology is based on passing alternating current with duration of ~10-1…101 s through porous
(35…40%) blanks made by method of Sintering by Electric Discharge (SED) by passing a pulse
of current with duration of ~10-5…10-3 s. The influence of technological regimes of porous blanks
treatment on their structure and properties is investigated. Geometry and dimension of contact necks
between powder particles of obtained samples are evaluated. Variations of porosity and strengths as
well as microstructure of porous samples materials before and after treatment are investigated.
Optimum range of treatment technological regimes is determined within which porosity of
30…35% with maximum strength values.
