What is Efeito Do Tratamento Criogênico Na Dureza e No Comportamento À Tração Do Aço AISI 4140 about?

This study investigates the impact of cryogenic treatment on the hardness and tensile behavior of AISI 4140 steel, comparing deep cryogenic treatment (DCT), shallow cryogenic treatment (SCT), and conventional heat treatment (CHT). Results indicate that while cryogenically treated specimens exhibit higher hardness, their tensile strength is lower compared to conventionally treated steel, attributed to the transformation of retained austenite to martensite. The research aims to enhance the mechanical properti
