Effect of Mn concentration on the kinetics of strain induced precipitation in Ti microalloyed steels

Effect of chemical composition on microstructure, strength and wear resistance of wire deposited Ni-Cu alloys

“…This could result from a lower carbon and nitrogen contents in FM60, and a possible increase in solubility of Ti in FM60 due to increased Mn content. In Timicroalloyed steels the rate of Ti particle precipitation has been shown to decrease with an increase in Mn content [27,28]. The particle sizes were in the range of 200-800 nm for all deposition speeds.…”

Precipitation Strengthening in Ni–Cu Alloys Fabricated Using Wire Arc Additive Manufacturing Technology

“…However, precipitation of TiC in FM60 had to be slower not only because of the lower C content but also because of the higher Mn content. Mn was reported to increase solubility of Ti in face-centered cubic lattices [21,22]. A decrease in the relative amount of Mn-rich particles and increase in TiAl-rich ones in FM60 after annealing and ageing at 610 • C could be due to the dissolution of some Mn-rich particles and the growth of fine TiAl-rich ones to the sizes large enough for observation in SEM.…”

Correlative analysis of interaction between recrystallization and precipitation during sub-critical annealing of cold-rolled low-carbon V and Ti–V bearing microalloyed steels

“…For the annealing condition of 800 o C 0 s, velocity of grain boundary is estimated using first order approximation [63] as explained below. Apart from Mn solute drag effect on recrystallization, there could be other direct (for example, Mn-C dipole formation [77]) or indirect factors (for example, precipitation [66,[78][79][80][81][82][83] or texture [84]) of Mn solute atoms on recovery/recrystallization mechanism. Ushioda et al [77] have studied the role of Mn in delaying the recovery during annealing, where dissolved C from cementite combines with Mn to form Mn-C complex.…”

“…It is proposed that higher amount of Mn solutes increases the solubility of TiC precipitate in austenite phase [82,83] and delays precipitation kinetics. The effect of Mn solute content on precipitation kinetics in the austenite phase is well known [66,[78][79][80][81][82][83], however there are not any conclusive data published on the Mn solute content effect on the precipitate solubility in the ferrite phase. The equilibrium precipitate volume fraction is plotted for the three grades for equilibrium state as shown in Fig.…”
