Advancing the Materials Genome

The term, Materials Genome (a registered trademark of MaterialsGenome, Inc., Pennsylvania, USA) was coined by the present author in 2002 and recently used with consent in the “Materials Genome Initiative” by the White House Office of Science and Technology Policy. In this paper, the author’s perspectives on Materials Genome, i.e. the building blocks of materials, will be illustrated with several related projects in the past. How Materials Genome helped us understand materials phenomena and materials design are demonstrated with examples such as cementite dissolution, carbide multi-phase miscibility gap, magnetic properties, INVAR phenomena, and negative thermal expansion. The concept of structural configurational entropy and its importance in affecting properties of individual phases are presented.
