Avaliação da conformabilidade e da resistência à indentação dos aços Intersticial Free High Strength Steel (IFHSS) e Bake Hardenable (BH) da classe de 260 MPa de limite de escoamento
(Universidade Federal de Minas GeraisUFMG, 2014-04-24)
The steel industry has as a challenge, to support the automotive industry to reduce the amount of pollutant emission and increase safety of vehicles, the development of steels of lower thickness, with medium and high ...
Effects of several TIG weld repairs on the axial fatigue strength of AISI 4130 aeronautical steel-welded joints
(Wiley-Blackwell, 2012-03-01)
Welded joints of airframes critical to the flight-safety are commonly repair welded during its operational live. In this study, the effect of up to three weld repairs by gas tungsten arc welding (GTAW) on the axial fatigue ...

Influence of boronizing treatment on Fe-Mn-Al-Si-C steel
(2016-01-01)
Austenitic Fe-Mn-Al-Si-C steel provides excellent cold formability and lower density compared to conventional stainless steels. These steels owe their corrosion and oxidation resistance to their aluminum and silicon contents, ...
Fatigue behavior of bainitic and martensitic super clean Cr–Si high strength steels.
(Oxford, 2014-04)
This study compares the fatigue behavior of quenched/tempered and austempered super clean Cr–Si high strength steels (HSS). The microstructure of the quenched and tempered steel consisted of tempered martensite and that ...
Nitretação por plasma do aço inoxidável ISO 5832-1 com fluxo intermitente de nitrogênio
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia MecânicaUTFPR, 2018-12-12)
Austenitic stainless steel is widely applied in industry due to its high resistance to corrosion and wearing. The thermochemical technique of nitriding by plasma at low temperatures focus to enhance wear resistance and ...
Effects of electroplated zinc-nickel alloy coatings on the fatigue strength of AISI 4340 high strength steel
(2005-12-01)
It is well known that fatigue behaviour is an important parameter to be considered in mechanical components subjected to constant and variable amplitude loadings. In combination with corrosion phenomenon, fatigue effects ...
Fatigue Performance of AISI 4340 Steel Ni-Cr-B-Si-Fe HVOF Thermal Spray Coated
(2015-01-01)
Coatings are deposited on high strength materials to improve the surface degradation resistance of several elements. As a consequence, the fatigue strength of coated materials is significantly influenced by internal residual ...
