Comparison of Creep Behaviour and Microstructural Changes in Electrodeposited Ultrafine-grained Nickel and its Particle-reinforced Nanocomposite

Popis výsledku v původním jazyce

On the basic of the creep experimental results the paper reports comparison creep behaviour of electrodeposited ultrafine-grained nickel and its particle-reinforced nanocomposite. The objective of this research was to further improve the knowledge of thecreep behaviour of monolithic nickel and to explore the role of nano-sized SiO2 particles in the potential creep strengthening of electrodeposited Ni nanocomposite. The creep behaviour and microstructure of the pure ultrafine-grained nickel and its nanocomposite reinforced by 2 vol.% nano-sized SiO2 particles were studied at temperatures in the range from 293 to 573 K and at the tensile stresses between 100 to 800 MPa. It was found that the creep resistance of the nanocomposite might be noticeably improved compared to the monolithic nickel. Possible creep mechanisms controlling the creep rate during the creep loading were discussed. The Coble creep as creep rate controlling mechanism was founded improbable.
