Recent Research Achievement
(1) Using EMTO-CPA method, we investigated the phase stability and elastic modulus of titanium based alloys. We showed that transition metal elements (Nb, Ta, Mo, etc.) stabilize the beta phase over the omega phase while hardening the elastic modulus of the beta phase. Simple metal alloying elements such as Sn stabilize the beta phase over the omega phase but keep the elastic modulus unchanged. Based on this research we proposed that rationally designed beta Ti-TM-SM alloys might be candidates for human-bone replacement that requires low elastic modulus (APL. 2008; 93: 121902), which was confirmed by experiments.
(2) We investigated systematically the composition dependent elastic modulus and phase stability of X2YZ type of ferromagnetic shape memory Heusler alloys. We showed that the tetragonal shear modulus C' is a better predictor of the composition dependent TM than the number of valence electrons per atom (e/a) since the general TM~C' correlation works for some of the alloys for which the TM~e/a correlation fails, although there exist several cases for which both the general TM~ C' and TM~e/a correlations break down. An approach combing the experimentally determined modulation function and coherent potential approximation was proposed to determine the complex 5-layer modulated (5M) structure of the martensite. The non-modulated martensite β''' with the tetragonality of the unit cell c/a>1 is shown to be globally stable whereas the 5M martensite with c/a<1 is metastable. With the relative stability of different phases, the composition dependent TM of the Ni2MnGa-based alloys may be qualitatively explained. (see Science China: Technological Sciences. 2012; 55: 295 for review)
(3) We proposed a hardness model for the covalent/ionic solid solutions. With this model, the trend of the hardness of TiN1-xCx, TiN1-x, VN1-x, etc., as function of the composition has been successfully predicted. (APL. 2007; 91: 121918),
