Abstract :

Pzyrygrm flexible base alloy Fe-36Ni in the cast condition and the presence 05/0 and 04/0 wt% wt% aluminum, titanium in the temperature range ° C1150-850 with strain rate s-101/0 were studied. Microstructural studies showed that the addition of aluminum, aluminum-containing deposits such as aluminum oxide structure significantly increases. This strain has been focusing deposits suitable locations, as well as Qflshdn grain boundaries that are leading to the loss of flexibility. Titanic also formed deposits of titanium dioxide and titanium nitride grain size reduction and enhanced flexibility Pzyrygrm.
