Расчет температурных и силовых параметров локального деформирования трубчатой заготовки при фрикционном нагреве и влияние их на микроструктуру полученного изделия

Abstract

The deformation of the tubular blank friction tool – a process which is characterized by localization of the plastic deformation, the value of the zone of influence which is significantly less than the deformable portion of the preform. In this process, deformation zone moves continuously along the pipe surface, symmetrical cross-sectional shape of which in the deformation process is not saved. The analysis of the contact area of the tool to the workpiece, given the factors affecting the running effort, and the basic components of effort running. The mathematical calculation of the main components of the effort and determined the nature of the break-force distribution running on time. A graphical representation of the efforts of the running of time for different combinations of factors affecting the run-in.The analysis of the microstructure of billets at frictional heating and comparing the data with the results of microanalysis preform is heated by induction heating.
