Elaboração e análise de indicadores bibliométricos de publicações na área de educação em engenharia de materiais
(Universidade Federal de São Carlos, 2021-11-08)
Engineering is directly related to the industrial and socioeconomic development of each country and region in which it operates, being a central area in its development. Indispensable to the present day, the engineering ...
Ligas multicomponentes do sistema Ti33Cr37V30-xNbx (X: 0, 5, 10 e 15) para armazenamento de hidrogênio
(Universidade Federal de São Carlos, 2021-11-30)
The use of metal hydrides is a competitive alternative to hydrogen storage in liquid or gaseous states. Metallic alloys based on the TiCrV system have attractive hydrogen storage characteristics compared with those of the ...
Comportamento de oxidação em temperaturas elevadas de ligas NiTiNb com efeito memória de forma
(Universidade Federal de São Carlos, 2021-09-10)
Shape memory alloys (SMA) of the Nickel-Titanium (NiTi) system are currently the most commercially important, due to their excellent mechanical properties, high shape recovery and biocompatibility. Such a unique set of ...
Design of high entropy alloys for hydrogen storage: study of the Mg-V-Al-Cr-Ni, Mg-Al-Ti-Mn-Nb and Ti-V-Nb-Cr systems
(Universidade Federal de São Carlos, 2021-05-21)
The advent of high entropy alloys (HEA) has brought new opportunities and challenges to metallurgy. Due to extensive compositional field of HEAs, the possibility of controlling properties in a composition-driven approach ...
Avaliação das microestruturas de solidificação e propriedades de aplicação de ligas monotéticas Al-Bi, Al-Bi-Cu e Al-Bi-Zn
(Universidade Federal de São Carlos, 2021-06-16)
Monotectic Al-based ternary alloys can result in a good combination of wear resistance and mechanical strength. While the soft self-lubricating elements contribute to an appropriate wear resistance, modification with third ...
Avaliação da anomalia da teoria de nucleação clássica em vidros silicatos
(Universidade Federal de São Carlos, 2021-07-13)
Under some conditions, the Classical Nucleation Theory (CNT) provides a good description of the temperature dependence of the experimental homogeneous nucleation rates in supercooled liquids. Allegedly, however, it strongly ...
Método de controle de trajetória de atuadores ipmc baseados em nafion® utilizando técnica de visão de máquina em ambiente com umidade relativa controlada
(Universidade Federal de São Carlos, 2021-08-13)
Ionomeric polymer-metal composites (IPMC) consist of an electroactive polymeric matrix coated on both sides with a noble metal. When applying an electrical potential difference, the polymeric membrane changes its thickness, ...
