Blades with molybdenum silicides withstand higher temperatures

Temperature dependence of yield stress of DS MoSi2/Mo5Si3 eutectic composites Temperature dependence of yield stress of DS MoSi2/Mo5Si3 eutectic composites

Tantalum, added composite molybdenum silicides helps boost material resilience of turbine blades, as tested by scientists at Kyoto University. Advanced compositions of molybdenum silicides improve the strength of blade materials at temperatures around 1,400 degrees Celsius (°C ). By contrast, nickel-based turbine blades, used in similar combustion systems, already melt at temperatures 200°C, or lower, and require significant air-cooling.
