“…It can also be seen that the adiabatic shear bands produced by shear slip. The formation of serrated chips and shear bands was observed during the machining of titanium alloy, which complies with the finding of other studies [25,26]. The reason for the formation of serrated chips and shear bands in the machining of titanium alloy is that the thermal softening effect of titanium alloy is greater than that of the strain hardening effect and strain rate strengthening effect [9].…”

“…With respect to the Johnson-Cook law, an additional term (S) modeling the strain softening has been added. The values of constants in the Johnson-Cook law (A, B, C , n, m) are obtained from Shivpuri and Hua (2001).˙ 0 represents the reference strain rate, Tr and Tm, the room and melting temperatures, respectively. The constant 0 can modulate the strain corresponding to the peak stress.…”
