Study on adiabatic shearing sensitivity of titanium alloy in the process of different cutting speeds



The cutting experiments were conducted for the industrial pure titanium (TA2) and titanium alloy (Ti-6Al-4V) under the same cutting condition to obtain different chip shapes. The energy barrier formed adiabatic shear band (ASB) was calculated. It shows that the smaller the energy barrier, the stronger the adiabatic shearing sensitivity and the easier the occurrence of serrated chip. The mechanisms of action of different alloy elements for adiabatic shearing sensitivity and surface roughness were studied. For TA2, its adiabatic shearing sensitivity is low because of low strength and high thermal conductivity. The shape of the chip is approximate ribbon. For Ti-6Al-4V, the bi-phase interfaces are caused, strength is increased, and thermal conductivity is decreased due to Al and Ti addition, so its adiabatic shearing sensitivity is higher than that of TA2. The serrated chip divided uniformly by ASB was formed. By and large, there is a positive correlation between adiabatic shear sensitivity and surface roughness in the other same conditions. The basis can be provided for optimizing process parameters, improving surface quality, and selecting materials by studying the specific alloy elements on the influence of adiabatic shearing sensitivity to some extent.
