The effect of severe plastic deformation processing on creep properties of metallic materials

Popis výsledku v původním jazyce

This paper investigates the effect of different ECAP routes and number of ECAP passes on resulting microstructure, mechanical properties and creep behaviour of selected materials. The distinction between various ECAP routes with different number of ECAPpasses applied may lead to variations both in the macroscopic distortions of the individual grains and in the capability to develop a reasonably homogeneous and equiaxed UFG microstructure. Experimental materials were processed by ECAP at room temperature using a die with an internal angle of 90°between the two parts of the channel. The ECAP pressing was performed by different routes up to 12 ECAP passes. Tensile creep tests were conducted at temperatures 473 - 673 K and at different applied stresses. Microstructure of samples was characterized by SEM-EBSD. In conclusion, the ECAP processing route and number of applied ECAP passes could play an important role in creep behaviour and their effect may be different for particular materials.
