Effect of yttrium addition on phase transformations in alloy 718

Autor: Rosa Maria Sales da Silveira, Alessandra Vieira Guimarães, Clarissa Hadad de Melo, Rafaella Martins Ribeiro, Alexandre Bellegard Farina, Loïc Malet, Luiz Henrique de Almeida, Leonardo Sales Araujo

Publikováno v: Journal of Materials Research and Technology, Vol 18, Iss , Pp 3283-3290 (2022)

The nickel-base alloy 718 is widely used due to its superior performance at high temperatures, combining properties such as high strength, high corrosion and oxidation resistances and good formability and weldability. Its properties can be further im

Hydrogen Effect on Zr-Nb-Mn Alloys for Nuclear Reactor Application

Autor: Thais de Brito Pintor, Frederico Simkevicius Gabriel, Rafaella Martins Ribeiro

Publikováno v: Materials Research, Vol 22, Iss suppl 1 (2020)

Zr-Nb-Mn alloys were developed to investigate hydrogen diffusion and its effects among different manganese additions. Thermo-Calc® and TC-Prisma simulations were used to determine the studied chemical compositions and to estimate the volume fraction

Hydrogen Kinetics and Hydride Formation Effect on Zr-1Nb and Zr-1Nb-1Sn-0.1Fe Alloys for Nuclear Application

Autor: Leandro Martins de Oliveira, Rodrigo Vitorino da Silva, Dilson Silva dos Santos, Rafaella Martins Ribeiro

Publikováno v: Materials Research, Vol 20, Iss suppl 2, Pp 786-791 (2018)

The purpose of this study was to investigate the kinetics of hydrogen absorption and hydride formation and their effect on the mechanical properties in Zr-1Nb and Zr-1Nb-1Sn-0.1Fe alloys, which were thermomechanically processed and gaseously hydrided

Hydrogen gas permeation through amorphous and partially crystallized Fe40Ni38Mo4B18

Autor: Rafaella Martins Ribeiro, Luis Fernando Lemus, Dilson Silva dos Santos

Publikováno v: Materials Research, Vol 15, Iss 5, Pp 818-820 (2012)

Samples of amorphous and partially crystallized Fe40Ni38Mo4B18 alloy were submitted to hydrogen gas permeation from 523 to 643 K. The hydrogen permeation curves exhibited a single sigmoidal shape, typical of tests where no hydride formation occurs. I
