Processing of Porous NITI Preforms for NITI/MG Composites
Archives of Metallurgy and Materials, 2019 NiTi alloys are successfully used in engineering and medical applications because of their properties, such as shape memory effect, superelasticity or mechanical strength. A composite with Mg matrix, due to its vibration damping properties, can be characterized by low weight and good vibration damping properties.
