New titanium alloy discovery extends fatigue life, revolutionizing aerospace industry.
The study looked at how creep (slow deformation over time) and fatigue (repeated stress) affect a new titanium alloy called Ti-6211. They found that a little bit of creep before fatigue can actually make the material last longer. Holding the material at a certain strain level can also help it resist fatigue. However, holding it at a constant stress level doesn't make a difference unless it's cycled many times. They also discovered that cyclic loading can speed up the creep process compared to just leaving the material under a constant load.
