“…The Young's modulus at 600 • C and 800 • C was obtained from the slope of the tensile stress-strain curves (Fig. 4) as described in other studies [25,26]. The approximated Young's modulus was 110 GPa and 105 GPa at 600 • C and 800 • C, respectively.…”

“…The Young's modulus of each alloy at 600°C and 800°C was obtained from the slope of the tensile stress-strain curves (Figure 3), as described in other studies. [27,28] The approximated average Young's modulus for A1 was 90 and 15 GPa at 600°C and 800°C, respectively. For A2, the Young's modulus was 50 and 20 GPa at 600°C and 800°C, respectively.…”

This study examined the high-temperature degradation behavior of two types of heat-resistant Si-Mo ductile cast iron (Fe-3.4C-3.7Si-0.4Mo and Fe-3.1C-4.5Si-1.0Mo) with particular attention paid to the mechanical properties and overall oxidation resistance. Tension and lowcycle fatigue properties were examined at 600°C and 800°C. The mechanical tests and metallographic and fractographic analyses showed that cast iron containing higher Si and Mo contents had a higher tensile strength and longer fatigue life at both temperatures than cast iron with lower levels due to the phase transformations of pearlite and carbide. The Coffin-Manson type equation was used to assess the fatigue mechanism suggesting that the higher Si-Mo alloy was stronger but less ductile than the lower Si-Mo alloy at 600°C. However, similar properties for both alloys were observed at 800°C because of softening and oxidation effects. Analysis of the isothermal oxidation behavior at those temperatures showed that mixed Fe 2 SiO 4 layers were formed and the resulting scaling kinetics was much faster for low Si-Mo containing iron. With increasing temperature, subsurface degradation such as decarburization, voids, and cracks played a significant role in the overall oxidation resistance.

“…Nb as additional element has some problems such as high cost and high density. Efforts have been made to reduce the Nb content of Ti-22Al-27Nb alloy by substituting Nb with other alloying elements, such as W and Mo [8,9]. The present authors have found that multiple additions of Mo and Fe are effective to reduce Nb content and also to improve tensile and creep strength at elevated temperatures up to 923 K [10].…”
