Original abstract

High entropy alloy AlCoCrFeNiTi0,5 was produced by combininng high energy mechanical alloying (MA) and spark plasma sintering (SPS) processes. One of the most important parameters determining final properties of final products is sintering temperature. In our study we have investigated the effect of four different sintering temperatures (ranging from 1150 to 1300 ºC) on microstructures and microhardness of bulk samples by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vickers microhardness test. Very good densification in all cases was recorded revealing small influence of sintering temperature on all properties.

Czech abstract

Zliatina AlCoCrFeNiTi0,5 bola vyprodukovaná Mechanickým legovaním (MA) a SPS spekanním. Jedným z najdôležitejších parametrov určujúcich konečné vlastnosti konečných produktov, je teplota spekania. V našej štúdii sme sledovali vplyv štyroch rôznych spékacích teplotách (v rozmedzí od 1150 do 1300 ° C) na mikroštruktúry a mikrotvrdosť vzoriek pomocou röntgenovej difrakcie (XRD), skenovacej elektrónové mikroskopia (SEM), a mikrotvrdosti
