This study investigates the microstructure and high-temperature strength of Fe-Al-Si(-Mo) alloys with the incorporation of refractory metal additives such as molybdenum. The objective was to understand the effects of alloying elements and heat treatment on the overall mechanical properties, particularly yield stress under high-temperature conditions. Methodologically, the research involved a series of experiments including tensile and compression tests on samples subjected to varying heat treatments, specifically long-term annealing and short-term annealing at high temperatures. The results demonstrated that the addition of tantalizing elements like vanadium and tungsten led to a significant enhancement of yield stress values within the temperature range of 700-800 °C, underscoring the importance of these elements in alloy design for high-performance applications. Furthermore, it was found that long-term annealing at 800 °C resulted in a slight decline in yield stress due to the precipitation of secondary particles, while short-term annealing at 1200 °C yielded the highest yield stress values across tested alloys due to new phase nuclei formation. This research provides insights into the mechanisms of strengthening in Fe-Al-based alloys and their potential applications in high-temperature environments.
