Aluminum alloys – strong, tough, and lightweight – are desirable materials for aerospace, marine, and defense applications. When processed using laser powder bed fusion, however, these alloys have a tendency to crack and distort. To mitigate this problem, EWI recently tested blending AA7075 with AlSi10Mg powder. The results show great promise for successful laser additive...

EWI, GE Research (GER), and the University of South Carolina (U of SC) have just begun a $5 million program funded by the Department of Energy in which machine learning is used to develop the process for building a functionally graded material for energy applications. The specific goal is to develop net-shape manufacturing technologies for...

How can you harness the power of high-power ultrasonic technology to optimize your manufacturing processes? EWI Project Engineer Amin Moghaddas recently developed a technique using special resolution V design and RSM to characterize and optimize ultrasonic-assisted drilling for aluminum 6061. This work is discussed in his paper, Modeling and Optimization of Ultrasonic-Assisted Manufacturing Process. You...
