The purpose of this work is to study the short-term mechanical properties of Fe-Cr-Al-Si-based alloys. Within the framework of this work, alloys with a chromium content of 5 to 14 wt%, aluminum from 0 to 4 wt%, and silicon from 0 to 4 wt% are considered. The samples were tested in three different states -in the deformed state (cold rolling by 80%), and also after annealing at a temperature of 450 and 650 ∘ C with a duration of 1000 h. As a result, the characteristics of the strength and

... ty of alloys in the deformed state, as well as after provoking annealing, were obtained. It is shown that embrittlement isn't observed in the investigated composition region and annealing conditions, and the strength of the alloys is directly proportional to the sum of the alloying elements Al + Si.
