Structure and properties of Fe-Ni-Al-Si alloys produced by powder metallurgy

Popis výsledku v původním jazyce

Reactive sintering powder metallurgy is a simple alternative to conventional melting and powder metallurgy processes. During this process, pressed powder mixture of pure metals or other precursors is transformed into bulk intermediary phases by thermallyactivated in situ reaction. This process was previously tested on Fe-Al and Fe-Al-Si alloys. Positive effect of silicon on the reactive sintering behaviour was determined, leading to the development of novel carbon-free high-silicon FeAl20Si20 alloy (given in wt%). In this work, the effect of nickel on the pressureless reactive sintering of Fe-Al-Si pressed powder mixtures was studied. To explain the nickel influence, differential thermal analysis was utilized. Microstructure, phase composition and porosity of the FeAl20Si20Nix (x = 0, 5, 10, 20 wt%) alloys was described. Hardness, wear resistance, high-temperature oxidation resistance and thermal stability were evaluated as functions of nickel content. Results showed that porosity dec
