The research focuses on the solid-state displacement reactions in Mg/SiO2 diffusion couples leading to the spatiotemporal self-assembling of product phases. Two different models are proposed in the literature to explain this phenomenon - either the concept of “concentration fluctuation” in the diffusion zone or mechanism based on possible influence of the stresses.
The experiment performed in the differential scanning calorimeter thanks to the high vapor pressure of magnesium allow to obtain the sample without use of any external pressure. So far in the literature, the experimental verification of the phase composition was uncertain. It is also important to mention that the “concentration fluctuation” model assumption is strictly related to the phase composition of the periodic layers. Therefore, presented verification of the phases by means of TEM is of essential need.
The research was financed by the National Science Centre, Poland under the project No. 2014/15/B/ST8/00195.
