IWAMOTO, Gerson Yoshinobu; RODRIGUES, Christiane de Arruda; IWAMOTO, Luciana Aparecida de Sousa  e  VIEIRA, Rogerio de Almeida. New Peritectoid Reaction Identified at the MnSb Alloy. Mat. Res. [online]. 2019, vol.22, suppl.1, e20180647.  Epub 11-Abr-2019. ISSN 1980-5373.  https://doi.org/10.1590/1980-5373-mr-2018-0647.

The tunable Tc region of MnSb alloy (44 - 49 % at. Sb) was analyzed using OM, VSM, DSC, XRD, EDS and XRF characterization techniques. Thermal and magnetic analysis suggests the existence of a non reported irreversible reaction on heating, compatible to a reverse peritectoid transition MnxSb ➔ Mn2Sb + Mnx'Sb.

Palavras-chave : Magnetic materials; phase transformation; MnSb metals and alloys; manganese-antimony alloys; Curie Temperature; perictetoid transformation.
