Experimental techniques for rapid collections of materials data and holistic approaches to integrate experimental and computational data will be described with examples. Localized property measurements on composition gradients created in diffusion multiples allow high-throughput collection of several materials properties as a function of composition, in addition to phase diagrams and diffusion coefficients.

A novel approach was developed to rapidly establish reliable diffusion coefficient (atomic mobility) databases by holistically integrating both experimental and computed data. Dual-anneal diffusion multiples allow rapid and systematic collection of big datasets of phase precipitation kinetics and morphological evolution across wide ranges of compositions as a function of time and temperature. An approach that iteratively and holistically integrate experimental results with model predictions can be the most effective in both establishing materials databases and understanding of various mechanisms.

Ji-Cheng Zhao is a Minta Martin Professor of Engineering and Chair of the Materials Science and Engineering Department at the University of Maryland. He was a Program Director at the Advanced Research Projects Agency – Energy (ARPA-E) from 2014 to 2017 and was a professor at Ohio State from 2008 to 2014 and also from 2017-2019. Before academia, Dr. Zhao was a materials scientist at GE Research Center for 12 years (1995- 2007) where he introduced Thermo-Calc to GE 25 years ago and initiated the high-throughput diffusion multiple approach. Zhao holds 49 issued U.S. patents and was the 2001 winner of the prestigious Hull Award from GE. He is a Fellow of both ASM and MRS, and received the 2021 TMS William Hume-Rothery Award that “is presented annually to recognize a scientific leader for exceptional scholarly contributions to the science of alloys”.
