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：帕特里克柯伦：EP/L016273/1英国和加拿大已正式宣布气候紧急状态;清洁能源生产在应对气候变化方面至关重要。海上风电为英国和加拿大提供了一种可行的绿色能源生产方法。钛合金提供比钢更持久的结构材料，但钛是昂贵的。从航空航天废料中回收钛是一种经济有效的高性能材料的绿色来源。场助烧结技术是一种新的钛回收工艺，可以方便地回收钛.冲击波和腐蚀性环境的结合破坏了海上可再生能源结构。在这个项目中，我们调查海洋环境对目前使用的钢和回收钛的裂纹生长的影响，通过弯曲钛和钢在海洋环境中，并使用创新的非接触技术，如数字图像相关测量裂纹生长。我们预计，目前使用的钢中的裂纹扩展将比回收的钛更快。这将意味着由钛制成的风力涡轮机将具有更长的寿命，并产生更多的绿色能源，这将使其具有成本和能源效益。
