Mapping of chromite occurrence in a meta-ultramafic complex by magnetometric prospecting, Sul-Riograndense Shield (Southern Brazil) = Mapeamento de ocorrência de cromita em complexo metaultramáfico por meio de prospecção magnetométrica, escudo Sul-Riograndense (Sul do Brasil)

Resumo: Este estudo apresenta a utilização do método de magnetometria terrestre na caracterização de rochas ultramáficas metamórficas e mineralizadas com cromo na região de São Sepé (RS). As rochas mais preservadas são serpentinitos cinzentos a verdeescuros e ocasionalmente xistos magnesianos Leia mais…

Tailoring phase transformations in SAE 9254 steel: a dilatometry-based study on austenitization quenching, and carbon partitioning processes

Abstract: This study investigates the phase transformations and microstructural development of SAE 9254 steel subjected to various heat treatments aimed at achieving a combination of bainitic, martensitic, and retained austenitic phases. The critical austenitization and quenching temperatures, along with the Leia mais…
