Phase Transitions in Relaxor Ferroelectrics
This paper covers the properties of relaxor ferroelectrics and considers the transition from the paraelectric state to the relaxor state comparing experimental data with the spherical random-bond randomfield model (SRBRF). It found that this model predicts and is experimental verifies a glassy state at the transition temperature for E < Ec and a ferroelectric state with quench random fields for...
متن کاملThermotropic phase boundaries in classic ferroelectrics.
High-performance piezoelectrics are lead-based solid solutions that exhibit a so-called morphotropic phase boundary, which separates two competing phases as a function of chemical composition; as a consequence, an intermediate low-symmetry phase with a strong piezoelectric effect arises. In search for environmentally sustainable lead-free alternatives that exhibit analogous characteristics, we ...
متن کاملUrban Transformation: a Changing Phase of Minna Central Area, Nigeria
Urban centres in the world are undergoing facets of changes, these changes are evident in developing countries and more divergent because urban transformation in developing countries is often accompanied challenges which include traffic congestion, overcrowding, pollution and continuous land use succession. This phenomenon is not different with the central area of Minna, Nigeria. Since 2008 the...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولPHASE TRANSFORMATION DURING WEAR OF AISI STAINLESS STEEL 316
Abstract: Austenitic stainless steels exhibit a low hardness and weak tribological properties. The wear behaviour of austenitic stainless steel AISI 316 was evaluated through the pin on disc tribological method. For investigating the effect of wear on the changes in microstructure and resistance to wear, optical microscopy and scanning electron microscope were used. The hardness of the worn...
