The free energy chatlge associated with the omega transformation is described using a Born-van Karman anharmonic planar lattice model. It is shown that a dual-phase longperiod &ructure cowisting

NATURE OF THE OMEGA TRANSFORMATION\* K E. COOK? The symmetry change associated with the b.c.c. to omega transformation is examined using the Landau criterion for a second order reaction. The ordering parameter 11 is defined in terms of the transformation displacements such that the structure defined

A phenomenological theory of transformation superplasticity is presented from the point of view of thermomechanics. The stretching tensor and entropy density are assumed to be decomposed into the elastic part and the part due to the superplastic process. The constitutive equations for the superplas

Buckingham and Fairbank s describe extremely accurate measurements of the specific heat of liquid helium which show that the 2 transition is not of second order, the specific heat undergoing a logarithmic infinity superposed as a step discontinuity of -5.2 J/g/deg.K. The logarithmic infinity is too
