Aksom P. Improvement of the properties of renewable parts of vehicles

This paper addresses the scientific and technical problem of expanding the use of austenitic steels for the manufacturing and restoration of parts of vehicles. Was studied the joint effect of cold plastic deformation and vegetable lubricant-coolant liquids during the machining. The paper determined reasons for improvement of workability, which consist in preliminary execution of part of the work of cutting by plastic chipless deformation, increase of dislocation density by 1-3 orders, partial transformation of paramagnetic structure of austenitic steel into ferromagnetic, due to the change of contact processes on the front surface of the tool. The method of transverse three-dimensional compression of metallic materials was developed and the ranking of environmentally friendly lubricant-coolant materials was performed, among which rapeseed oil was the best liquid.
