This Small Business Innovation Research (SBIR) Phase II research project will develop a prototype Induced Positron Manufacturing Damage System (IPMDS) to be used to assess initial component quality, and manufacturing damage effects for Ti-6Al-4V and IN738 components. The IPMDS is based on the Induced Positron Annihilation technologies whose capabilities to assess alpha inclusion and fatigue damage effects have been previously demonstrated. The IPMDS is an innovative damage assessment tool that will be developed with support from Precision Cast Corporation (PCC) as a manufacturing quality control and damage assessment tool to be used to reduce costs in place of current destructive methods, which are expensive and do not provide adequate sensitivity to either manufacturing or operational damage effects. The IPMDS will contribute to extended use component designs, cost savings, and efficient operations for the titanium and nickel super-alloy industries. Commercial applications of IPMDS will be targeted at the structural and turbine engine industries, which extensively utilize expensive titanium and nickel super-alloy components. The IPMDS has a high potential for becoming a critical and necessary inspection tool in these industries due to its potential for minimizing manufacturing variability, assessing operational damage, optimizing maintenance requirements, reducing costs, and improving safety. The IPMDS capability is expected to extend inspection applications to a wide range of industries where improved knowledge of manufacturing variability, induced damage effects, minimization of inspection and replacement costs, and component life extension are important.

这项小企业创新研究（SBIR）第二阶段研究项目将开发一个诱导正电子制造损伤系统（IPMDS）原型，用于评估Ti-6Al-4V和IN738组件的初始组件质量和制造损伤效果。IPMDS基于诱导正电子湮灭技术，其评估α夹杂物和疲劳损伤效应的能力已被证明。IPMDS是一种创新的损伤评估工具，将在精密铸造公司（PCC）的支持下开发，作为制造质量控制和损伤评估工具，用于降低成本，取代目前昂贵的破坏性方法，这些方法对制造或操作损伤影响都没有足够的灵敏度。IPMDS将为钛和镍超合金行业的扩展使用组件设计、成本节约和高效运营做出贡献。IPMDS的商业应用将针对结构和涡轮发动机行业，这些行业广泛使用昂贵的钛和镍超合金部件。IPMDS有很大的潜力成为这些行业的关键和必要的检查工具，因为它有可能最大限度地减少制造变化，评估操作损坏，优化维护要求，降低成本，提高安全性。IPMDS的能力有望将检测应用扩展到广泛的行业，在这些行业中，提高了对制造变异性、诱发损伤影响、最小化检测和更换成本以及延长组件寿命的认识是很重要的。
