1. Effect of the Chemical Homogeneity of a Quenched and Tempered C-Mn Steel Pipe on the Mechanical Properties and Phase Transformations
Seamless steel pipes for application in the oil and gas industries are manufactured from quenched and tempered steel. Aiming to meet the required characteristics, it is necessary that the microstructure and the mechanical properties are homogeneous along the wall thickness of the pipes, which is even more critical for thick wall pipes. Considering the seamle

2. Heat Treatment of Sintered Valve Seat Inserts
The characterization of sintered valve seat inserts (VSIs) after being subjected to different heat treatment operations has been carried out. The VSIs were obtained from three different alloys by mixing iron powder with AISI M3:2, AISI M2 high-speed steels, and AISI D2 tool steel. After sintering, the VSI were quenched in air followed by double tempering at

3. Cinética de envelhecimento de aços dual phase de baixa resistência mecânica laminados a frio
The kinetics of static strain aging in cold rolled Dual Phase steels of the 250/450 MPa grade of mechanical strength was studied by means of tensile tests. Two Dual Phase steels, with and without a chromium addition of 0.36wt%, were studied in a pilot scale. After the continuous annealing step, carried out in a Gleeble machine model 3500, the specimens were

5. Lógica nebulosa (fuzzy) aplicada na determinação dos parâmetros de trabalho de fornos industriais de têmpera contínua para o aço CK 75. / Fuzzy logic applied in the determination of the parameters of work of industrial furnace of continuos tempering of the steel CK75.
Este trabalho apresenta o projeto de um sistema gerador de "set-point" (GSP), utiliza-do na determinação dos parâmetros de trabalho de fornos industriais de têmpera contínua de aços ao carbono, cuja modelagem é baseada na lógica "fuzzy". O trabalho é constituído de três etapas básicas: primeiro, estudou-se os princípios metalúrgicos do aço e d
