Dr. Rajiv Mishra, Regents Professor in Material Science and Engineering at University of North Texas will give a seminar titled "Convergence of Computationally Designed Alloys and Processes at the Onset of Space Inhabitation Era" to the interested faculty and students at Discovery Park.

Abstract

The evolution of alloy design and process innovation in first half of the last hundred years was primarily empirical. The computational approaches in the last 50 years have accelerated the pace of discovery exponentially. In the last century, the production of metals at increased volumes established the statistical approach of qualification and certification. While the capabilities and capacity to come up with new alloy composition increased, the qualification of new alloys for structural applications became a hinderance. As we embark on an era of permanent presence in space and on moon, the discovery of high entropy alloys has created unprecedented compositional space. In parallel, additive manufacturing is going to disrupt the conventional supply-chain. Manufacturing can now be done at the point-of-need and digital imprint can change the qualification approach. In this overview presentation, I will capture a few examples of the path travelled and what lessons we can take to build a future that discovers and uses structural materials more effectively. Can machine learning and artificial intelligence be used to completely alter the current discovery-use paradigm? Can qualification and certification be largely digital? What fundamentals can we use to enable such a vision?
