Structure and morphology of metals are designed by metallurgical methods to develop new metals for medicine with high biocompatibility and excellent biological function.

  1. Phase of metal is controlled to be the non-equilibrium states such as glassy and nano-crystalline phases by mean of the non-equilibrium process.
  2. Surface or whole body of metal is controlled to be porous with less toxicity by mean of the dealloying technique.

Development of highly functional medical metallic materials by combining advanced metal processing technique and state-of-the-art 3D additive manufacturing technology

In order to establish advanced medical technology, it is important to study highly functional metallic materials as biomaterials. Our laboratory combines EBM technology, which is the cutting-edge three-dimensional modeling technology, with basic technologies such as plastic working such as forging and rolling processing used in the development of general industrial materials and heat treatment technology. Using the latest analytical techniques and computer simulation, we are developing metallic materials for high performance medical use, through systematic studies on microscopic and nanoscale structural changes occurring inside the material, based on the mechanism of characteristic expression.
