Comparative topographic study of surface micro-relief of primary martensite plates in shape memory alloys with different crystalline structures
The surface micro-reliefs of primary martensite plates, representative for two shape memory alloys (SMAs) with different crystalline structures were compared from qualitative and quantitative point of view by scanning electron microscopy and atomic force microscopy, respectively. Qualitative evaluations revealed larger widths and heights of the primary plates of e hexagonal close packed (hcp) martensite, in an Fe-Mn-Si-Cr-Ni SMA than those of b29
Read moreInfluence of temperature variation rate on calorimetric response during heating and on martensite structure obtained after subsequent cooling of Cu-Zn-Al shape memory alloy
The calorimetric response of a martensitic Cu-Zn-Al-Fe shape memory alloy (SMA) was evaluated during second heating, up to 453 K, with different rates ranging between 1.67 × 1022 and 1.67 × 1021 K s21, performed on a differential scanning calorimeter (DSC). Heating rate (HR) variation caused a marked change of the endothermic peak aspect, which was observed on the DSC thermograms recorded during second heating and associated with the martensite

In this paper we show that the local monotonicity in the sense of Minty and Browder on some residual sets assure the global monotonicity and, according to an earlier result, the convexity of the inverse images. We pay some special attention to the residual sets arising as complements of some special first Baire category sets, namely the sigma-affine sets, the sigma-compact sets and the sigma-algebraic varieties. We achieve this goal gradually by

Neurofilaments usually associated with neural tissues are the type IV family of intermediate filaments. Nestin, which is a type VI intermediate filament, is a well known marker of endothelial cells in newly formed blood vessels and is developmentally and structurally related to type IV intermediate filaments. We aimed to determine whether or not cardiac endothelial cells (ECs) label with antibodies for neurofilaments (200 kDa, Novocastra-Leica, clone
