The influence of the composition of iron-based alloys on the microhardness of the areas of the melted metal in explosion-welded joints with aluminum is investigated. It is shown that, other things being equal, the presence of chromium in the composition of an iron-based alloy leads to an increase in the hardness of the alloys by 1-2 GPa, and joint alloying with chromium and nickel, by 3 GPa.
