Which element is known for reducing creep in metals?

Molybdenum is recognized for its effectiveness in reducing creep in metals due to its unique properties. Creep is the tendency of a solid material to slowly deform under the influence of constant stress, particularly at high temperatures. Molybdenum enhances the creep resistance of alloys, especially those used in high-temperature applications, because it helps to stabilize the microstructure of the metal at elevated temperatures.

The addition of molybdenum in steel and other metal alloys improves high-temperature strength and maintains stability, allowing these materials to perform better under challenging conditions. This is particularly important in applications such as turbine engines and reactor components, where materials are subjected to extreme temperatures and pressures.

Other elements listed may have their own benefits or uses in metallurgy, but for specifically reducing creep, molybdenum is the most effective choice.
