Investigation of the Influence of Various Kinds of Hardening on the Surface Structure EI893

Article Preview

Abstract:

The paper presents data on investigation of the microstructure of the surface of EI893 alloy samples on a Jeol JSM-6390A scanning electron microscope after different types of processing: annealing, thermoplastic hardening and surface plastic deformation. The change of structure and thickness of the hardened layer is shown, depending on the type of surface treatment
