Assessment of the austemperability of high-silicon cast steels through Jominy hardenability tests
(Maney Publishing, 2018-11)
The austemperability of seven high silicon cast steels with different alloy contents was characteri sed. The maximum round bar diameter that can be fully austempered changed from about 10 mm for an unalloyed steel to more ...
Effect of carbon content on microstructure and mechanical properties of dual phase steels
(Elsevier, 2015-08)
Dual-Phase steels (DP) are constituted by a ferrite matrix with a martensite fraction, giving a good combination of strength, ductility, capacity of energy absorption and strain hardening. Mechanical properties arecontrolled ...
An experimental study of steel fiber-reinforced high-strength concrete slender columns under cyclic loading
(2012-08-10)
Structural engineers usually limit the use of HSC columns to seismic active zones because of their britle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ...
Development of ultra-high strength carbide-free bainitic cast steels
(Maney Publishing, 2020-11)
High-silicon cast steels and proper heat treatment cycles were designed in order to obtain carbide-free bainitic microstructures. The design process allowed to obtain the desired microstructures after heat treatment cycles ...
Estimation of the fracture toughness threshold of a ferritic steel at the lower ductile to brittle transition region
(Universidade Federal de São Carlos, 2016-09)
The ADN420 ferritic steel (A615 steel Grade 60 [420]), used as reinforcing bars (rebar) in concrete, shows the so called ductile to brittle transition. Room temperature is located on the lower third region of the transition ...
Corrosion behavior of martensitic and precipitation hardening stainless steels treated by plasma nitriding
(Elsevier Science Sa, 2010-07)
Plasma nitriding is a well established technology to improve wear and corrosion properties of austenitic stainless steels. Nevertheless, in the case of martensitic stainless steels, it continues being a problem mainly from ...
Ultrasonic fatigue tests at high temperature on an austenitic steel
(Elsevier Ltd, 2012-12)
The objective of this paper is to study the gigacycle fatigue behavior of an austenitic steel at temperatures of 600 °C and 700 °C under fully reverse loading (R=−1). Numerical simulation by finite element method (FEM) was ...
Influence of roughness on the tribological behavior of a steel- steel couple lubricated with thread compound
(Planta Piloto de Ingeniería Química, 2019-07-31)
The purpose of this study is to determinate the influence of surface roughness on the tribological behavior of a lubricated steel against steel tribosystem. Tests were carried out at high pressure and slow sliding speed, ...
Behaviour of steel-fibre-reinforced normal-strength concrete slender columns under cyclic loading
(2012-03-28)
The inclusion of ductility requirements is necessary to guarantee a safety design of concrete structures subjected to unexpected and/or reversal loads. It is important to outline that plastic hinges may develop in columns ...
