Outline of Final Research Achievements

The purpose of this study is to improve the strength of commercially pure titanium by low temperature nitriding. To diffuse nitrogen into pure titanium even at low temperature, crystal grains of titanium were refined by a severe plastic deformation process. Low temperature nitriding increased surface hardness and low temperature nitrided specimen showed higher strength compared to the conventional nitrided one. This is because the low temperature nitriding suppresses the grain-coarsening of pure titanium and forms a nitrogen compound with lower Young's modulus.
