An overview of the microstructures present in high-speed steel - Carbides crystallography
The aim of the work was to prepare an overview about the microstructures present in high-speed steel, focused on the crystallography of the carbides. High-speed steels are currently obtained by casting, powder metallurgy ...
Energía de fractura en modo I del concreto reforzado con fibras cortas de acero a partir de un ensayo de tracción directa
(Universidad de La Salle. Facultad de Ingeniería. Ingeniería Civil, 2017)
Análise estrutural de vigas mistas treliçadas do tipo steel-joist warren modificada
In this work, the failure capacity and the rupture mode of a simply supported mixed truss beam steel-joist modified warren type has been determined. The mixed steel-concrete trusses, which are very efficient to overcome ...
Austenite transformation and age hardening of HSLA-80 and ULCB steels

Determination of the volume fraction of retained austenite in a 300m steel by heat tinting technique
Applying the Heat Tinting Technique the microestrutural characterization of a 300M steel (medium carbon steel) was accomplished. The steel was austenitized for 20 min to 900°C, followed by holding at 400°C (in the bainitic ...
Corrosion effects on pullout behavior of hooked steel fibers in self-compacting concrete
Fiber reinforced concrete structures are subjected to chloride and carbonation penetration that could initiate corrosion of steel fibers, with eventual pernicious consequences in terms of structural and durability performance. ...
Reliability-based evaluation of design guidelines for cold-formed steel-concrete composite beams
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2010)
This paper presents an analysis of design guidelines for steel-concrete composite beams, formed by concrete-filled cold-formed steel sections. The study is based on experimental results for connector resistance (push-out) ...
Numerical and experimental analysis of tubular plane trusses for use in a standardized roof system with long span
