Melting-Casting Furnace for Structure Control
This apparatus consists of three parts for each process, that is, melting furnace, water-cooling copper mold for casting and water spray-zone. Continuous experiments through melting, deoxidation, casting, and cooling with various experimental conditions can be conducted by using this apparatus, and the effect of composition of molten steel, kind of inclusion, and solidification or cooling rate on microstructures of casting can be investigated.

Shear Added-Rolling Simulator
This rolling mill is able to introduce both compressive strain and shear strain. Conventional rolling, cross roll rolling, and differenct speed rolling is possible.
By using Shear Added-ROlling Mill, grain size, texture, mechanical properties of rolled place and so on are different from those in case of conventional rolling.
|
|
* Cross roll rolling:
Share strain through plate thickness by making upper and lower roll intersect. Maximum cross angle is 10 degrees.
* Different speed rolling:
The share strain through place thickness by changing upper and lower roll velocity.

Multidirection Drformation Thermomechanical Treatment Simulator
Multi axis processing is an effective method for the refinement of the grains and the randomization of the texture. This machine can process a series of the rotating and forging specimens.
It is possible to forge into a different direction at each process. We examine the relation between the multi functional processing and the refinement or the texture of the grains.
|
|
* Mechanisms
This machine has the following three mechanisms and can simulate the rolling and forging process.
(1) Processing mechanismwhich used two hydraulic Actuators (Maximum lead 25 ton/ Maximum speed 2m/s)
(2) Heating mechanism which used direct energizing and high frequency electricity heating.
(3) Mechanism which rotates the specimen

Characterization Equipment for Deformed Crystalline Microstructure
Multifunctional Microstructure Characterization Equipment Composed of Scanning Electron Microscope (SEM), Orientation Imaging Microscope (OIM) and Energy Dispersion Spectroscopy (EDS).
EBSP (Electolon Bac-Scattering diffraction Pattern) appears as the result of the interaction of incident electron beam and crystalline material. The orientations of micro-scale regions can be obtained and the crystal orientation and phase distribution in the materials can be mapped and analyzed. Meanwhile, the element distribution in the materials is characterized quantitatively with EDS.
