Subject Overview


The goal of 3.044 is to teach cost-effective and sustainable production of solid material with a desired geometry, structure or distribution of structures, and production volume. Toward this end, it is organized around different types of phase transformations which determine the structure in various processes for making materials, in roughly increasing order of entropy change during those transformations.



Solid Heat Treatment


This section will take advantage of the mathematical similarity between diffusion and heat conduction to introduce you to the phenomenon of heat transfer by conduction, convection and radiation. These tools will provide understanding on how to induce or avoid the various chemical reactions, precipitation, annealing and other solid-state phase transformations learned in 3.022.



Liquid-Solid Processing


Most large-scale processes for making solids involve the liquid state at some point, and the initial microstructure formed during the liquid-solid transition often persists into the final part. This section will deal with solidification and precipitation/coating reactions from solution, with a focus on the mechanisms which determine structure in this processing step.



Fluid Behavior


Fluid behavior and fluid-solid interactions are crucial to understanding many processes. This section will focus on concepts of drag force on solids and fluids in relative motion, from particles to flat surfaces to porous media. It will close with a discussion of overall mass and momentum balances on large control volumes.



Deformation Processing


This section will introduce mechanical deformation processes from sheet forming to sintering, which provide opportunities for inexpensively forming very advantageous structures on a large scale. It will build on concepts from the previous section to treat deforming solids as moving fluids, and also deformation mechanisms discussed in 3.032.



Vapor-Solid Processing


As the transformation with the largest entropy change, vapor-solid processes present unique opportunities for precise control of structure.



Special Topics


3.044 will close with a set of lectures summarizing and contextualizing course material and placing it in the context of society at large.
