Designing Steels to Mitigate Failure during Ballistic Deformation (Summary Technical Report, Oct 2018-Sept 2021)

Abstract

This summary technical report presents an overview of the key research activities, major technical outcomes, and impact from the 3-year basic research program entitled Designing Steels to Mitigate Failure during Ballistic Deformation. This program was successful in developing institutional knowledge and a framework for the design of novel ultrahigh strength steels for enhanced ballistic performance using transformation-induced plasticity and twinning-induced plasticity. Engineering of the austenite volume fraction and stability through alloy design and controlled processing identified future pathways for production of enhanced performance armor steels. The advanced understanding of the phase transformation has potential applications beyond armor as well.
