The current task of engineering is to ensure the quality and reliability of critical parts of an extended cylindrical shape. This task is especially relevant in the production of power hydraulics parts for mining equipment (ME). One of the ways to ensure the required quality of the surface layer (SL) of mining equipment parts is the use of combined and joint methods of parts hardening by surface plastic deformation (SPD). Combined methods present sequential machining in which the methods used are separated into different technological steps, while the joint machining is carried out by concentrating the methods into one technological step (setup). The analysis shows that this approach, although it has a number of indisputable advantages, allowing an increase in the accuracy, machining efficiency and SL quality, is not without drawbacks that hinder the use of combined and joint machining methods in the manufacture of parts with IT 8-9 accuracy. The dimensional joint running- in method (DJR) is based on the original scheme of interaction between the cutting and deforming tools allowing a cylindrical surface with an accuracy of IT 8-9 and a roughness of no more than Ra 0.4 μm, hardened to a depth of 10 mm in one pass. The study shows the possibilities of a much greater SL deformation without its destruction than with the traditional SPD. The analysis of the structure and basic technologies has shown the feasibility of replacing a number of turning and grinding operations with one dimensional joint running-in operation. The design of the device for DJR based on a lathe is given. The completed economic calculations have established that it is possible to implement this method in the existing economic situation.

“…Compared to models on quasi-static deformation of austenitic and martensitic SMAs, models for high strain rate deformation of SMAs have not been fully developed [55][56][57][58][59][60][61]. By considering jump conditions and wave functions, Chen and Lagoudas [55] established a one-dimensional model for stress wave propagation of SMAs under dynamic loading.…”

A three-dimensional model for phase transformation of shape memory alloys (SMAs) during high strain rate deformation is developed and is then calibrated based on experimental results from an austenitic NiTi SMA. Stress, strain, and martensitic volume fraction distribution during high strain rate deformation are simulated using finite element analysis software ABAQUS/standard. For the first time, this paper presents a theoretical study of the microscopic band structure during high strain rate compressive deformation. The microscopic transformation band is generated by the phase front and leads to minor fluctuations in sample deformation. The strain rate effect on phase transformation is studied using the model. Both the starting stress for transformation and the slope of the stress-strain curve during phase transformation increase with increasing strain rate.
