1. Identificación de Fases y Precipitados por MFA en Uniones de Acero Inoxidable Dúplex
Abstract Atomic Force Microscopy (AFM) is a characterization technique that generates topographic images of surfaces at very high resolutions, and operates recording details of surface relief of material with a cantilever that moves on the sample, while a piezoelectric detector monitors changes in height. It acquires relevance in the field of identification

2. Numerical dynamic analysis of stiffened plates under blast loading
Using the general purpose finite element package Abaqus, an investigation has been carried out to examine the dynamic response of steel stiffened plates subjected to uniform blast loading. The main objective of this study is to determine the dynamic response of the stiffened plates considering the effect of stiffener configurations. Several parameters, such

3. Evaluation of energy absorption performance of steel square profiles with circular discontinuities
This article details the experimental and numerical results on the energy absorption performance of square tubular profile with circular discontinuities drilled at lengthwise in the structure. A straight profile pattern was utilized to compare the absorption of energy between the ones with discontinuities under quasi-static loads. The collapse mode and energ

4. Linear dimensional changes in plaster die models using different elastomeric materials
Dental impression is an important step in the preparation of prostheses since it provides the reproduction of anatomic and surface details of teeth and adjacent structures. The objective of this study was to evaluate the linear dimensional alterations in gypsum dies obtained with different elastomeric materials, using a resin coping impression technique with

7. Características mecânicas de vergalhões de aço auto-revenido
The rebar steel is one of the most utilized and diffused materials in Brazilian civil construction, as it is in the whole world, but it´s necessary to know more details about the rebar behavior as a material and not only as a structural element. Each day civil engineering searches for new alternatives to maximize the use of materials, from new structural ca

8. Evaluation of the transformation mechanisms and mechanical properties of ferrite: martensite microalloyed steels
The influence of starting point microstructures on the transformation mechanisms and mechanical properties of a micro alloyed steel after annealing in the alpha + gamma region have been investigated. Three different microstructures: austenite, pearlite in a ferrite matrix and martensite were used as starting point microstructures for the production of dual (

9. Automation and integration CAD/CAE on the design of steel structures, using hollow sections / Automação e integração CAD/CAE no projeto de estruturas metalicas, utilizando perfis tubulares
This work has as objective to show a software that have the goal to automate the main stages of a steel structural design, using AutoLISP and Delphi5 languages. The steel structural designs in case are the roofs formed by plane trusses made by hollow sections frames. These hollow steel sections, which are not highly used in plane structures in Brazil, are be

10. Erosion-oxidation behavior of thermal sprayed Ni20Cr alloy and WC and Cr3C2 cermet coatings
An apparatus to conduct high temperature erosion-oxidation studies up to 850 °C and with particle impact velocities up to 15 m.s-1 was designed and constructed in the Corrosion Laboratories of IPEN. The erosion-oxidation behavior of high velocity oxy fuel (HVOF) sprayed alloy and cermet coatings of Ni20Cr, WC 20Cr7Ni and Cr3C2 Ni20Cr on a steel substrate ha

11. Estudo experimental da evaporação de jatos de iso-octano superaquecido. / Experimental study of evaporating jets of superheated iso-octane.
The main goal of this thesis is to present results of experiments with flashing liquid jets of iso-octane. The experiments were carried out with a liquid jet issuing from a small nozzle into a low-pressure chamber. High degrees of metastability were obtained as the liquid jet expanded within the nozzle. Injection pressure and temperature were controlled to t

12. Composite beam-column connection Theoretical and experimental analysis / Ligações mistas viga-pilar - análise teórica e experimental
A composite joint is a joint between a composite beam and a steel or composite column in which reinforced concrete slab is take into account. The moment-rotation relationship of composite joints depends on a significant number of parameters besides the type and configuration of the steel connection, as for example: the amount of steel reinforcement of the sl
