Effect of chromium concentration on microstructure and properties of Fe–3.5B alloy

▶ With the increasing chromium additions, the boride changes from Fe 2B to (Fe,Cr) 2B-type boride. ▶ The matrix of Fe–3.5B alloy transforms to supersaturated α-(Fe,Cr) solid solution when high chromium concentration is added. ▶ The fracture toughness of boride increases with the increase of chromium...
