Desenvolvimento de vitrocerâmicos transparentes resistentes ao impacto
(Universidade Federal de São Carlos, 2021-11-11)
Transparent glass-ceramics (GCs) can replace glasses traditionally used as ballistic windows and electronic displays due to their better mechanical properties. This improvement is obtained by the crystallization of phases ...
Design, production and advanced characterization of CoCrFeMnNi-based medium- and high-entropy alloys: understanding the interplay with composition, microstructure, and mechanical properties
(Universidade Federal de São Carlos, 2024-04-12)
Worldwide, a great research effort is being employed in the development of Medium/high entropy alloys (M/HEAs). Among the M/HEAs produced to date, great emphasis is given to the equiatomic Co20Cr20Fe20Mn20Ni20 (at.%) alloy ...

(Universidade Federal de São Carlos, 2004-08-12)
The influence of the injection molding parameters on the morphology and mechanical properties of poly(phenylene sulfide), PPS, and of a 80/20(%wt) blend of PPS/block copolymer styrene-ethylene-butylene-styrene ,SEBS, ...
Efeito do inoculante Al-Nb-B na microestrutura e propriedades mecânicas da liga AA2017 fabricada por fusão em leito de pó a laser
(Universidade Federal de São Carlos, 2023-01-24)
The blending of finer powders of Ti, Zr, Ta, Sc, and Nb compounds as inoculants has been a promising strategy to modify precipitation-hardened aluminum alloys for laser-based powder bed fusion process (L-PBF), promoting a ...
Influência da nióbia no óxido de alumínio eletrofundido para aplicações abrasivas
(Universidade Federal de São Carlos, 2021-07-29)
Abrasives are materials that have as main characteristics their cutting and
grinding power. In its most common crystalline form, aluminum oxide, due to its
high melting point, high hardness and mechanical resistance, ...
Estabilidade microestrutural da liga Cu-0,8Cr-0,07Zr após extrusão em canal angular em temperatura criogênica
(Universidade Federal de São Carlos, 2021-12-20)
Severe Plastic Deformation (SPD) are well established routes with regard to the
intense microstructural refining of metals and alloys up to the submicrometer (<
1 μm) and/or nanometer (< 100 nm) scales. Lowering the ...
Estudo do processo de soldagem a ponto por fricção de juntas dissimilares entre ligas de alumínio e titânio
