Alloying of C40-structured Mo(Si,Al)2 with Nb, Ta and V
Artikel i vetenskaplig tidskrift, 2023
Alloying of Mo(Si,Al)2, prepared by sintering, with Nb, Ta or V has been studied. All alloyed materials retained the C40-structured matrix phase of the un-alloyed reference material. The concentration of alloying elements in the C40 phase reached 0.4–1.6 at.% (approximately 20–50 % of the intended levels), and the remaining alloying content was dissolved in the minority D8m- and D88-structured (Mo,X)5(Si,Al)3 phases. V-alloying also promoted the formation of C54-structured (Mo,V)(Si,Al)2.
