Predicting Delta Ferrite Content in Stainless Steel Castings
(IRON STEEL INST JAPAN KEIDANREN KAIKANTOKYO, 2012)
The distribution of delta ferrite fraction was measured with the magnetic method in specimens of different stainless steel compositions cast by the investment casting (lost wax) process. Ferrite fraction measurements ...
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 ...
Mechanical properties of a carbide-free bainitic cast steel with dispersed free ferrite
(Maney Publishing, 2020-01)
A high silicon, medium carbon cast steel was designed and heat-treated in order to develop microstructures composed of carbide-free bainite and small amounts of free ferrite, with the aim of obtaining high strength cast ...
X-ray diffraction characterisation of expanded austenite and ferrite in plasma nitrided stainless steels
(MANEY PUBLISHING, 2010)
The S phase, known as expanded austenite, is formed on the surfaces of austenitic stainless steels that are nitrided under low temperature plasma. A similar phase was observed for nitrided ferritic stainless steels and was ...
Second Phase Precipitation in Ultrafine-grained Ferrite Steel
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014-03-01)
Grain size refinement is one of the most efficient strengthening mechanisms applied to modern High-Strength Low-Alloy steels (HSLA) because yield strength and toughness are both improved. This paper discusses the distribution ...
