强调了在安全至上的苛刻环境中采用新的或使用现有的先进合金系统的复杂性。特别重要的是能够定义可能限制部件寿命或功能的运行变形和退化机制。在基础材料科学方面，航空和发电部门之间有高度的共同性。大量新的实验和建模技术可以用来应对长期存在的技术挑战，为材料科学的复兴提供了潜力。在工业环境中，特别令人感兴趣的是能够通过最节能和最省时的路线‘设计’为服务用途而优化的材料微观结构和质地。总结了这一领域的要求和取得进展的潜力，重点是燃气轮机和核反应堆在六氟化碳金属方面的应用。
The complexity of adopting new or using existing advanced alloy systems in demanding environments where safety is paramount is highlighted. Of particular importance is the ability to define operative deformation and degradation mechanisms that may limit part life or functionality. With respect to the underlying fundamental material science there is a high degree of commonality between the aero and power generation sectors. The vast array of new experimental and modelling techniques that can be brought to bear on long standing technical challenges offers the potential for a renaissance in materials science. Of particular interest from an industrial context would be the ability to ‘design’ material microstructure and texture optimised for service use manufactured via the most energy and time efficient route. The requirements and potential for progress in this area is summarised with an emphasis on gas turbine and nuclear reactor applications for hcp metals.
