Rheological and surface properties of low-alloy chromium steels: high-temperature experimental study

Original language description

Chromium low alloy steels exhibit a favorable balance of enhanced corrosion resistance and mechanical strength, characteristics that are critically beneficial for a wide array of structural applications. The distinct properties of these materials, in conjunction with their cost-effectiveness, render low-alloy chromium steels particularly advantageous across numerous industries without compromising safety or performance. This work deals primarily with the rheological properties of low-alloy chromium steels in the high-temperature region, investigated using an Anton Paar FRS 1800 high-temperature rheometer, capable of recording rheological data up to 1,750 °C. The temperature dependence of viscosity, viscosity at temperature dwells and flow and viscosity curves were evaluated. The acquired data were systematically fitted using two distinct models: the Vogel-Tamman-Fulcher (VTF) model and the power-law (PL) model. Additionally, the investigation encompassed the surface properties and interactions of the studied steels with corundum refractory materials at the phase interface. Wetting tests were performed using a CLASIC heating microscope, and surface tension and wetting angles were monitored as a function of temperature. Subsequent to the high-temperature wetting tests, X-ray diffraction (XRD) analysis was performed on the corundum substrate surface to confirm the formation of new phases. Furthermore, this surface, together with the contact and free surfaces of the steel droplets, underwent detailed examination through Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) microanalysis.
