Dr. Peter Collins, Professor and Stanley Chair in Interdisciplinary Engineering at Iowa State University will speak at 1:30pm on Monday, January 31, 2022 in Brauer Hall, Room 12. 

An Integrated Computational Materials Engineering (ICME) framework has been developed and applied for multiple variants of large-area additive manufacturing of the aerospace alloy Ti-6Al-4V.  The approach permits the integration of (i) mesoscopic models of heat-transfer and a moving energy source with (ii) kinetic and thermodynamic models for the prediction of key aspects of the materials state and the subsequent (iii) uniaxial tensile properties and (iv) statistical methods of developing so-called “design allowable curves”.  This previous effort has demonstrated which aspects of the materials state seem to matter for this particular alloy, as well as correlated features that could be measured.  This knowledge can be used to provide new directions for fundamental research, including the development of a new microscope capable of conducting a variant of orientation microscopy over very large areas.
