    Abstract: This book comprises the selected proceedings of the 3rd International Workshop on Natural Hazards (NATHAZ’22), Angra do Heroísmo, Terceira Island, Azores, 2022. The book interests all researchers and practitioners in Earth Sciences, Volcanic Risks, Natural Hazards, Geoethics, Environmental Sciences and Engineering. Terceira is a volcanic island with volcanic systems with caldera (Cinco Picos, Guilherme Moniz, Santa Bárbara and Pico Alto central volcanoes) and an active fissural zone defined by various alignments of small volcanic cones, lava domes and fault zones. The agricultural landscape, the natural and forest reserve, as well as the natural pools make the island a unique place to visit. The historic downtown of Angra do Heroísmo is a UNESCO world heritage, and several iconic buildings witness the island’s geodynamic history. Natural hazards result from a threat of a naturally occurring event that will have a negative effect on humans. That damaging effect is often called natural disasters. Among the natural hazards and potential disasters to be considered are: earthquakes, volcanic eruptions, landslides, subsidence, floods, droughts and coastal erosion. In addition, anthropogenic hazards occur as a result of human interaction with the environment. They comprise technological risks due to exposure to hazardous substances in the environment. Natural systems in different frameworks require a comprehensive understanding of climatology, geology, hydrology and volcanic data, processes and dynamics. Thus, it is important to perform hazard and risk assessment studies to accomplish hazard mitigation. In addition, it highlighted the role of variability and climate change in Earth systems. Furthermore, an accurate understanding of the natural systems and interactions with engineering, geodiversity and natural resources is vital to the entire socioeconomic sector. This book is expected to offer an overview of natural hazards in model regions in Europe, America, Asia and the Atlantic islands. It gives new insights into the characterization, assessment, protection, and modelling of geological hazards, volcanic systems, urban areas, coastal zones and engineering approaches by international researchers and professionals. The scientific committee comprises lead geoscientists, natural hazards related practitioners, and academics worldwide. The main topics include: 1. Multi-hazards and risks: sustainable society, disasters and geoethics 2. Natural hazards and assessment: rock falls, landslides, urban planning and management 3. Sustainable Earth systems: hazards and climate change 4. Terceira Island geology and geodiversity: meeting volcanological hazards in the Azores.

    Abstract: This book gathers the proceedings of the 2nd International Workshop on Natural Hazards (NATHAZ'19), held in Lajes do Pico, Pico Island, Azores in 2019. Natural hazards constitute the threat of a naturally occurring event having a negative effect on human beings. These effects are often called natural disasters. Among the natural hazards and potential disasters to be considered are: earthquakes, volcanic eruptions, landslides, subsidence, floods, droughts and coastal erosion. In addition, there are anthropogenic hazards that occur as a result of human interactions with the environment. They include technological hazards, which occur due to exposure to hazardous substances in the environment. Grasping the behaviour of natural systems requires a comprehensive understanding of climatology, geology and hydrology data and dynamics. Thus, it is important to conduct hazard and risk assessment studies for meaningful hazard mitigation. Further, the book demonstrates that an accurate understanding of natural systems and interactions between engineering and natural resources is of vital significance to the entire socio-economic sector. This volume offers an overview of natural hazards in model regions in Europe, America, and Atlantic islands. Providing new insights on the characterisation, assessment, protection and modelling of geological hazards, water systems, urban areas and coastal zones, it represents a valuable resource for all researchers and practitioners in the fields of Geosciences, Hydrology, Water Resources, Natural Hazards, Environments and Engineering. Main topics include: 1. Natural Hazards and Disasters 2. Sustainable Water Systems and Climate Change 3. Technological Hazards and Engineering Design.

    Notes: The Shape Memory Effect on Ni-Ti thin films is strongly dependent on several factors:(i) chemical composition of the matrix, (ii) presence of precipitates and (iii) preferential orientation.Ni-Ti alloys derive their unique nonlinear and anisotropic mechanical behavior from stress-inducedmartensitic transformations, where the resulting strains are affected by crystallographic orientation.The influence of the texture on the transformation characteristics of Ni-Ti thin films is discussed onthe basis of models and experimental results of the literature. A brief review of the texture build-upon thin films obtained by different fabrication techniques (sputtering, melt spinning, diffusiontreatment of ultra-fine laminates, …) is presented. Details about in situ techniques allowing theidentification of the preferential orientation during the fabrication process are presented. Theprocessing parameters that more strongly influence the preferential orientation of the Ni-Ti thinfilms are identified. The mechanisms for the different microstructures are summarized and a specialemphasis is put on the type of preferential orientation and its evolution along the processing time

    Notes: Syntactic functionally graded metal matrix composites (SFGMMC) are a class ofmetallic foams in which closed porosity results from the presence of hollow ceramic microspheres(microballoons), whose spatial distribution varies continuously between the inner and the outersection of the part, thus resulting in a continuous variation in properties. In this work, aluminiumbasedSFGMMC rings were fabricated by radial centrifugal casting. The graded composition alongthe radial direction is controlled mainly by the difference in the centrifugal forces which act on themolten metal matrix and the ceramic particles, due to their dissimilar densities. In this case wherethe density of the SiO2-Al2O3 microballoons is lower than that of molten aluminium, the particlesshow a tendency to remain closer to the inner periphery of the ring. Thus the microballoon volumefraction increases along the radial direction of the ring from the outer to the inner periphery; inother words, the particle-rich zone is limited to an inner layer of the ring. Precursor conventionalMMCs were prepared by stir-casting from the constituent materials, by homogeneously dispersingcommercial SiO2-Al2O3 microballoons (particle size: 50 µm; particle volume fraction: 5 and 10 %)within a molten commercial Al-7Si-0.3Mg (A356) alloy. The resulting MMCs were then re-meltand centrifugally cast in order to produce the functionally graded composites. Particle gradients inthe centrifugally cast composites were investigated by quantitative image analysis of opticalmicrographs (for the estimation of the particle volume fraction, mean particle diameter and porosityvolume fraction)

    Notes: In the present paper, a selection of micrographs showing some typical microstructuresand corrosion layers developed in copper and bronze alloys from different archaeological contextswill be discussed. Metallurgic interpretation of the microstructures observed, based in the properbinary equilibrium phase diagrams is presented. Micro-EDXRF and SEM-EDS analysis werecarried out to assess the alloy composition and to contribute to the understanding of the corrosionprocesses occurred during the long periods of burial of the archaeological metals. Examples ofsurface decuprification, strong intergranular corrosion, cuprite under green corrosion layers andcopper redeposition indicate particular corrosion processes. The presence of copper oxides,sulphides inclusions, lead globules and porosities is also documented

    Notes: Shape memory effect (SME) in Nickel-Titanium (Ni-Ti) alloys is ascribed to thethermoelastic reversible martensite phase transformation. Phase transformation is established to beaffected by the pre- thermal and mechanical history of the alloy. The present work deals with theeffect of mechanical working, known as ‘marforming’ and ‘ausforming’, on the phasetransformation characteristics and mechanical behaviour of Ti-rich Ni-Ti alloy. Tensile study andmeasurement of the hardness data were carried out at room temperature. Mere heat treatment orheat treatment at 773 K after the marforming shows similar characteristics, whereas, the as-receivedand the ausformed samples exhibit different behaviours. Hardness numbers of the heat treatedsamples are found to be smaller than those of the as-received and mechanically worked samples
