High temperature compressive flow behavior of a Mo–Si–B solid solution alloy

Deformation behavior of a two-phase Mo–Si–B alloy

“…The large difference in atomic radius, however, will contribute in an appreciable way to substitutional solid solution hardening. Recent work by Jain et al [29] confirms this to be the case. Jain et al [29] evaluated a MoeSieB solid solution alloy in compression at 1000 C and 1200 C and compared its response to those of pure Mo and a two-phase MoeSieB alloy.…”

Jain et al [29] evaluated a MoeSieB solid solution alloy in compression at 1000 C and 1200 C and compared its response to those of pure Mo and a two-phase MoeSieB alloy. The potent solid solution strengthening capacity of Si was confirmed and the role of the matrix in strengthening the two-phase alloy was elucidated.…”

Microstructure and oxidation behavior of directionally solidified Mo–Mo5SiB2 (T2)–Mo3Si alloys

“…In Mo-Si-B ternary system, Mo-rich Mo-Si-B multiphase alloys consisting of Mo solid solution (Mo(ss)), Mo 5 SiB 2 (T2), and Mo 3 Si phases have received considerable attention because of their relatively good room temperature fracture toughness and high temperature creep resistance and strength [8][9][10]. Recently, the oxidation behavior of the Mo-T2-Mo 3 Si alloys has been extensively studied [11][12][13][14].…”

Oxidation mechanisms of lanthanum-alloyed Mo–Si–B

“…Silicides of Nb and Mo show the most attractive behavior with respect to high temperature oxidation resistance, and therefore, these materials are studied intensively [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Amongst these materials, the Mo-Si-B alloy [12][13][14][15][16][17][18][19][20][21][22][23][24][25] is the most promising candidate comprising of a three phase Mo ss (molybdenum solid solution) -Mo 5 SiB 2 (T2) -Mo 3 Si (A15) microstructure, which is stable up to temperatures of about 1600°C in non-oxidizing environment. The volume fraction of the individual phase in the alloy is dependent on the composition and hence the properties of interest.…”
