Two different types of Fe-base shape memory alloys (SMAs), obtained by different processing methods, were comparatively analyzed from the point of view of: (i) structural characterization, (ii) morphologic aspects and (iii) mechanical behaviour. For this purpose, heat treated specimens of Fe-9Cr-4Ni-0.33C and in Fe-28Ni-17Co-11.5 Al-2.5 Ta (mass. %) were produced and prepared for X-ray diffraction (XRD) and scanning electron microscopy (SEM) observations,

The heat treatments consisted of using three types of treatment atmospheres (air, nitrogen and argon) and three isothermal maintaining times (6 × 102 s, 24 × 102 s and 48 × 102 s). The

The tendency of developing and increasing active surfaces of the city are related to the population rapid growth in the big cities,
Read moreNew city is the new metropolis, built from scratch in the shape of a globalised and globalizing city which devours its surrounding tissue into a spatial pattern of ever-growing heights. This new city is the new three-dimensional space matrix, a space where horizontal expansion results into a spatial density exponential increase. New city is the denomination of architectural and urban phenomena, former city of the future, denoting a massive investment

The entire professional community, heritage commissions, and civil societies (in areas where this experience of urban life already exists) are trying
