 note = {Matrix algebra analysis of martensitic transformations has been employed for the determination of habit planes and shape deformations of Ca_2SiO_4 upon β-to-α´_L transformation during heating. The cell parameters of both the parent β and product α´_L-phases at the transformation temperature(710℃)have been found from extrapolation of the regression of their cell-parameter variations. The analysis indicates that one of the principal distortions(=c_<α´L>/3b_β)of the lattice deformation is equal to unity, and the other principal distortions are larger and smaller than unity. This satisfies the requirement for the formation of completely coherent interfaces between the two phases, which are almost parallel to either(100)_β or(001)_β. Because the transformation involves a very small volumetric expansion of 0.3%, the strain accommodation would be almost complated. Both the complete coherency at the interphase boundaries and the effective strain accommodation probably lead to the thermoelasticity of the transformation, in accord with a previous study for doped Ca_2SiO_4., application/pdf},
