The variation of strain rate sensitivity exponent and strain hardening exponent in isothermal compression of Ti–6Al–4V alloy

Graded microstructure and mechanical properties of additive manufactured Ti–6Al–4V via electron beam melting

“…(9) and (10) are not very appropriate. Furthermore, the n value is found to be highly dependent on strain and strain rate [51]. As suggested, there might be no such an alternative general hardness-strength conversion expression that is available for all materials [52].…”

Effect of microstructure on strain hardening and strength distributions along a Cr–Ni–Mo–V steel welded joint

“…Zhang et al [12] concluded that the strain hardening of metals was controlled by the mean free path of dislocation motion. When the Ti-6Al-4V alloy was subjected to isothermal compression, the strain hardening exponent was found to be strongly affected by the strain rate due to the variation of grain size of primary a phase [13]. Research findings still differs in how many stages of the work hardening exist in dual phase steels, though it has been related to different activated deformation mechanisms at strain range corresponding to each stage [14][15][16].…”

Advances in material and friction data for modelling of metal machining

“…However, till date, such testing methods have not . Ti-6Al-4V flow stress curves at 1303 K produced using the Thermecmaster-Z thermal-mechanical simulator [149]. been utilized by the machining research community.…”
