The samples were investigated by means of XRD, SEM, TG/DTA and porosity analysis. Compressive strengths of AAS samples before and after exposure to elevated temperatures ranging from 600 °C to 1000°C were determined. The significant microstructural modifications highlighted by changes in porosity due to the sintering process are responsible for the strengthening of AAS sample after heating at 600,800 and 1000°C. Moreover, in AAS sample after heating to and above 600 °C wüstite transforms to spinel. © 2014 Elsevier B.V. |
