Study on action mechanisms of alloy element for adiabatic shearing sensitivity
Source abstract
Abstract
The effect of specific alloy elements on adiabatic shearing sensitivity was studied by cutting experiment for the industrial pure titanium (TA2) and titanium alloy (Ti-6Al-4V) in the level of valence electron structure (VES). The valence electron structure (VES) parameters that affect adiabatic shearing sensitivity were studied in this paper. The results show the electron density of heterophase boundary and the lattice electron density are related to adiabatic shearing sensitivity. The higher the electron density of heterophase boundary, the lower the lattice electron density, the higher adiabatic shearing sensitivity, and the easier the formation of the serrated chips. The electron density of heterophase boundary and the lattice electron density have coupling effect on adiabatic shearing sensitivity. The adding of Al and V elements for Ti-6Al-4V can increase the electron density of heterophase boundary and reduce the lattice electron density, so its adiabatic shearing sensitivity is higher than that of TA2, which would produce easily serrated chips divided evenly by the adiabatic shear band (ASB) and enlarge the degree of serration to exacerbate the tool vibration.
