A study has been made of the superplastic tensile behaviour of a microduplex Ti–6AI–4V alloy in the temperature range 760–940°C. Maximum superplastic elongations were obtained for a temperature of 880°C at which the volume fraction of β–phase was approximately 0·4. At temperatures below about 850°C, the main microstru…

Abstract By integration of equations previously derived by Frank, the growth rate of polymer crystals is shown to be dependent on their size, provided that the persistence length L p or the kinetic length L k = (2 g / i ) 1/2 are significantly larger than the primary nucleus. A new method of decorating the fold surfac…

We present experimental evidence that during rapid deformation of at least some crystalline and polymeric solids heat is generated at unexpectedly high temperatures beginning essentially at the moment deformation begins. The heat was observed by fast infrared sensors. Both the initial infrared emissions and the appare…

The microscopic ``spin-gas'' model reproduces and physically explains the sequence of liquid-crystal phases, nematic--smectic-${A}_{d}$--nematic--smectic-${A}_{d}$ --nematic--smectic-${A}_{1}$, which was observed with decreasing temperature in recent experiments. The microscopic frustration inherent to smectic structu…

Abstract Upon shearing, some polymeric liquid crystals develop a particular texture, called “band texture,” consisting of fine equidistant black lines as viewed between crossed polarizers. In mesomorphic hydroxypropylcellulose–water solutions, these bands are due to relaxation of the shear. The band texture appears af…
