Additional information

Collaboration with IMR, China on their superelastic beta-Ti alloy now in human clinical trials, the benefit being its low effective modulus and hence reduction of the stress shielding issue that leads to implant loosening. Showed, to their surprise, that their alloy had properties found due to stress-induced martensite, linking to Phenomenological Theory of Martensite Transformations. Now followed up by groups at (INSA) Rennes, (ENSCP) Paris, Metz, IFW Dresden, IISc Bangalore, NIMS Japan, Tokyo, Tsukuba, Harbin. Demonstration of ESRF in situ X-ray synchrotron diffraction, effect of interstitial O on blocking shear in crystals – leading to Leadership Fellowship EP/H004882/1.
