Materials Morphology Control Lab
Machine-translated · View original
A lab studying metal forming, which shapes and deforms metals through processes such as rolling and forging.
AboutAbout the lab
Creating new materials through processing and deformation
The Materials Morphology Control Lab studies how to shape materials such as metals through metal forming, including rolling, forging, and extrusion.
The lab proposes and develops processing methods for creating the new materials needed in the next generation, such as lightweight eco-materials, highly workable materials, and ultrafine-grained materials.
At the same time, it is clarifying how a material's microstructure and properties are determined during processing, and developing methods to predict them.
The lab's website introduces it under the name "Utsunomiya Lab."
Key terms
- Metal forming
- A process that shapes a material by applying force to cause permanent deformation. It includes rolling, forging, and extrusion.
- Rolling
- A process that passes a material between rotating rolls to stretch it into a shape such as a sheet.
- Porous materials
- Materials with many pores inside. The lab's web pages also refer to them by a different Japanese term meaning "porous materials."
ResearchResearch themes
The lab proposes and develops material processes for creating the new materials needed in the next generation, such as lightweight eco-materials, highly workable materials, ultrafine-grained materials, and highly recyclable materials. It also studies methods for clarifying and predicting the guiding principles by which microstructure and properties emerge during these material processes.
*Illustrative imageDevelopment of High-Performance Mg Alloy Sheets
The lab found that high-speed rolling can turn magnesium alloys, which are difficult to work, into sheets. The rolled sheets show a fine microstructure and excellent mechanical properties, and ultra-high-speed rolling has made rolling at room temperature possible.
Microstructure Control through Shear Deformation
Some of the textures produced by shear deformation are industrially useful. Conventional methods require special equipment and have problems with warping and surface quality, so the lab proposes and develops differential-friction rolling and hybrid rolling.
*Illustrative imageSimulation of Heterogeneous Deformation
Deformation analysis of materials usually assumes that the material is homogeneous. The lab incorporates inhomogeneity into the finite element method and develops numerical analysis methods that quantitatively predict the nonuniform deformation arising inside materials.
*Illustrative imageFabrication of Porous Materials
The lab makes porous materials using metal forming. Copper and aluminum wires are placed in a copper tube and extruded, and the aluminum is then removed to obtain lotus-type porous copper. This method requires no heat treatment, and the pore shape and porosity are easy to control.
