Relação estrutura-propriedades-processamento de aços inoxidáveis martensíticos
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de Minas - Mestrado ProfissionalUFMG, 2021-08-18)
AISI 420 martensitic stainless steel is widely used in the cutlery industry due to its high hardness, wear resistance and excellent corrosion resistance, properties acquired when this steel is subjected to heat treatment ...
Effect of Post-weld Heat Treatment on the Mechanical Properties of Supermartensitic Stainless Steel Deposit
(Springer, 2016-12)
Supermartensitic stainless steels have good weldability and adequate tensile property, toughness and corrosion resistance. They have been developed as an alternative technology, mainly for oil and gas industries. The final ...
Austenite reversion kinetics and stability during tempering of an additively manufactured maraging 300 steel
(2019-10-01)
Reverted austenite is a metastable phase that can be used in maraging steels to increase ductility via transformation-induced plasticity or TRIP effect. In the present study, 18Ni maraging steel samples were built by ...
Optimization procedures in the design of continuous induction hardening and tempering installations for magnetic steel bars
(1998-12-01)
An inverse problem concerning the industrial process of steel bars hardening and tempering is considered. The associated optimization problem is formulated in terms of membership functions and, for the sake of comparison, ...

Effect of Combined Tempering and Aging in the Austenite Reversion, Precipitation, and Tensile Properties of an Additively Manufactured Maraging 300 Steel
(2021-01-01)
Maraging 300 is an ultrahigh strength steel with significant alloy addition, resulting in a martensitic matrix hardened by precipitation through aging treatment. In these steels, intercritical tempering can provide reverted ...
Análise da adesão de filmes depositados por PVD sobre o aço H13 com diferentes tratamentos térmicos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEngenharia MecânicaUTFPR, 2017-12-11)
Injection and aluminum extrusion molds are produced in its majority with hot work steels, amongst which one of the most utilized is the AISI H13. In order to improve the service life of the molds, surface treatments of the ...
