“…Porous Ti-based alloys are able to provide adequate macro/micro pores for bone ingrowth, vascularization, and flow transport of nutrients and metabolic waste [ 173 , 174 ]. Calculations indicate that the introduction of porous (closed-cell or open-cell porosity) structure in dense materials might bring not only relatively high strength and larger plasticity but also lower elastic modulus [ 175 , 176 ].…”

Ti-based alloys are finding ever-increasing applications in biomaterials due to their excellent mechanical, physical and biological performance. Nowdays, low modulus β-type Ti-based alloys are still being developed. Meanwhile, porous Ti-based alloys are being developed as an alternative orthopedic implant material, as they can provide good biological fixation through bone tissue ingrowth into the porous network. This paper focuses on recent developments of biomedical Ti-based alloys. It can be divided into four main sections. The first section focuses on the fundamental requirements titanium biomaterial should fulfill and its market and application prospects. This section is followed by discussing basic phases, alloying elements and mechanical properties of low modulus β-type Ti-based alloys. Thermal treatment, grain size, texture and properties in Ti-based alloys and their limitations are dicussed in the third section. Finally, the fourth section reviews the influence of microstructural configurations on mechanical properties of porous Ti-based alloys and all known methods for fabricating porous Ti-based alloys. This section also reviews prospects and challenges of porous Ti-based alloys, emphasizing their current status, future opportunities and obstacles for expanded applications. Overall, efforts have been made to reveal the latest scenario of bulk and porous Ti-based materials for biomedical applications.

“…Стопи системи Ni-Zr широко використовуються як функціональні матеріяли, особливо в біомедицині, водневій промисловості, при виготовленні ядерних реакторів та паливних елементів [1][2][3][4][5]. Можливим шляхом модифікації технологічно важливих властивостей таких матеріялів є зміна їх атомної структури, зокрема аморфізація.…”

Для аналізи процесу аморфізації в системі Ni-Zr застосовано методу ab initio молекулярної динаміки із розглядом як еволюції атомарної структури, так і змін електронних спектрів. Положення атомів у надкомірці Ni21Zr11 було змодельовано шляхом числового відпалу за допомогою теорії функціоналу густини в узагальненому ґрадієнтному наближенні. Обговорюються зміни гістограми міжатомових віддалей надкомірки Ni21Zr11 за фазових переходів «кристал-рідина-аморфна фаза». Показано, що значна варіяція локального оточення атомів (до 30% від середнього значення в межах першої координаційної сфери) приводить до помітної варіяції локальних електронних спектрів для «аморфної» фази. Доведено незастосовність електронного критерію Наґеля-Таука у випадку аморфних стопів на основі Ni-Zr, що демонструють найвищу термічну стабільність.Ключові слова: перехідні метали, фазові переходи, аморфні стопи, електронна структура, ab initio молекулярна динаміка.

Self-propagating high-temperature synthesis (SHS) or combustion synthesis (CS) is a rapidly developing research area. SHS materials are being used in various fields, including mechanical and chemical engineering, medical and bioscience, aerospace and nuclear industries. The goal of the present paper is to provide a comprehensive state-of-the-art review and to analyse a critical mass of knowledge in the field of SHS materials and coatings. We also briefly discuss the history and scientific foundations of SHS along with an overview of the technological aspects for synthesis of different materials, including powders, ceramics, metal-ceramics, intermetallides, and composite materials. Application of CS in the field of surface engineering is also discussed focusing on two main routes for applying SHS to coating deposition: (i) single-step formation of the desired coatings and (ii) use of SHSderived powders, targets or electrodes in the coating deposition processes.
