| Abstract Scope |
Mechanical alloying under a cryogenic environment (cryomilling) has been established as one of the crucial severe plastic deformation processes for obtaining bulk nanomaterials. The use of cryogenic liquids facilitates the creation of a low-temperature environment which suppresses cold welding, promotes particle fragmentation, and limits oxidation, thereby enabling the formation of ultrafine grains. Understanding the thermomechanical state of the materials becomes essential to optimize the process; however, real-time tracking of these conditions presents a significant challenge. Therefore, computational simulations have become crucial for investigating particle interactions during mechanical alloying. This work presents a simulation of a laboratory-scale cryogenic ball mill using the discrete element method (DEM) coupled with a heat transfer model, to process two sets of materials, focusing on the collision energy and its impact on the strain of the processed materials. |
