Abstract

Abstract:

To explore the micro?scale removal mechanism of precision turning nickel?based single crystal superalloy， the simulation model of nickel?based single crystal turning by the diamond tool was firstly established after an analysis of the simulated physical characteristics based on the molecular dynamics simulation method by large?scale atomic/molecular parallel simulators， and the chip formation mechanism during the simulation process of nickel?based single crystal turning was analyzed by using an open visualization tool. Then the experimental research on the removal mechanism of nickel?based single crystal superalloy was carried out. The accuracy of the removal mechanism simulation results is confirmed by the transmission morphology and diffraction analysis of the subsurface microstructure of nickel?based superalloy. The simulation and test results indicated that the mechanisms of plastic removal in the process of turning nickel?based single crystal superalloy are structural damage to amorphous evolution， structural damage to dislocation stabilised stacking faults and structural damage to polycrystalline phase transition.

Key words: nickel?based single crystal superalloy, precision turning, removal mechanism, molecular dynamics simulation, structural evolution
