Representative Inventions/Developments

We introduce some of the major research achievements of IMR

2021

Hanada, MasahashiDevelopment of TiNbSn alloy for implant stems

TiNbSn alloys are characterized by suppressed stress shielding, which can cause fractures and loosening of implantable hip joints. It is composed of elements with low Young's modulus and low cytotoxicity. The alloy has been successfully commercialized through joint research with companies and Tohoku University Graduate School of Medicine.

AokiDiscovery of Multiple Superconductivity in Uranium Compounds

The uranium compound UTe₂ was found to have multiple superconducting phases under pressure and to be a spin-triplet superconducting state with multiple order variables. This multiple superconducting phase can be contrasted with the multiple superfluid phase of helium-3, which led to the Nobel Prize in Physics.

World record magnetic field of 25.1 Tesla generated by a cryogen-free hybrid magnet

This cryogen-free superconducting magnet combines a bismuth-based high-temperature superconducting coil and a high-strength niobium-3 tin conductor coil to generate a 25.1 Tesla magnetic field in a 52 mm room temperature space. This magnet enables long-term, high-precision experiments combined with cryogenic temperatures and high pressures.

2012

ChibaDevelopment of new class of Co–Cr-based alloys: COBARION®

COBARION® is a medical cobalt alloy used for artificial joints and other applications. It contains very little nickel, which causes metal allergies, and has excellent toughness, wear resistance, and corrosion resistance. Based on the research results of the institute, EIWA Co., Ltd. manufactures this alloy, and the Iwate Industry Promotion Center has trademarked it as COBARION.
