Increment of dislocation density that contributes to work hardening is calculated from the mean free path of dislocations. The mean free path is defined by the spacing of forest dislocations and the average spacing of dispersed particles. Obtained yield stress and work hardening characteristics was close to that of experimental result, except that the value of work hardening rate was higher than that of experimental one., 12th Asia-Pacific Conference on Engineering Plasticity and Its Application, AEPA 2014; Kaohsiung; Taiwan; 1 September 2014 through 5 September 2014; Code 107558}, pages = {264--268}, publisher = {Trans Tech Publications Ltd}, title = {Crystal plasticity analysis of mechanical response and size effect in two phase alloys with dispersion of fine particles}, volume = {626}, year = {2015} }
