EPSRC : Patrick Curran : EP/L016273/1The UK and Canada have officially declared a climate emergency; clean energy production is vital in combatting climate change. Offshore wind proves a viable method of green energy production for the UK and Canada. Titanium alloys offer longer lasting structural materials than steels, but titanium is expensive. Recycling titanium from aerospace waste offers a cost effective and green source of high-performance materials. A novel recycling process called field assisted sintering technology, can easily recycle titanium. The combination of crashing waves and corrosive environment, damages offshore renewable-energy structures. In this project we investigate the effects that the marine environment has on the growth of cracks in the currently used steels and recycled titanium by bending the titanium and steel within a marine environment and measuring crack growth using innovative non-contact techniques like digital image correlation. We expect that the crack growth will be faster in the currently used steel than recycled titanium. This would mean that a wind turbine made from titanium would have a longer lifetime and produce more green energy, which could make it cost and energy effective.

EPSRC：Patrick Curran：EP/L016273/1英国和加拿大已正式宣布气候紧急状态；清洁能源生产对于应对气候变化至关重要。事实证明，海上风电是英国和加拿大绿色能源生产的可行方法。钛合金提供比钢更耐用的结构材料，但钛价格昂贵。从航空航天废料中回收钛提供了一种具有成本效益的绿色高性能材料来源。一种称为现场辅助烧结技术的新型回收工艺可以轻松回收钛。汹涌的波浪和腐蚀性环境的结合会损害海上可再生能源结构。在该项目中，我们通过在海洋环境中弯曲钛和钢并使用数字图像相关等创新非接触技术测量裂纹扩展，研究海洋环境对当前使用的钢和回收钛中裂纹扩展的影响。我们预计目前使用的钢的裂纹扩展速度将快于回收钛。这意味着由钛制成的风力涡轮机将具有更长的使用寿命并产生更多的绿色能源，这可以使其具有成本效益和能源效率。
