Equilibrium Model of Precipitation in Microalloyed Steels
The formation of precipitates during thermal processing of microalloyed steels greatly influences their mechanical properties. Precipitation behavior varies with steel composition and temperature history and can lead to beneficial grain refinement or detrimental transverse surface cracks. This work presents an efficient computational model of equilibrium precipitation of oxides, sulfides, nitri...
متن کاملHigh Temperature Mechanical Properties of the As-cast Low Carbon Steels and Their Prediction
Steel undergoes multiple phase transformations during casting and various forces of technological origin affect a slab in the casting machine. As a consequence of these infl uences, various types of defects arise during the casting process [1 5]. The slab surface quality is a crucial factor for quality of the end products, especially of the fl at ones. Plasticity of the steel is a further, very...
متن کاملŠevčík: High Temperature Strength Analysis of Low Carbon Steels in the as - Cast State
High-temperature properties of the continually cast low carbon steel slabs are tested on various equipments [1 7]. The high temperature tensile strength test is the most used one and the primary evaluated quantity, plasticity, is mostly assessed by reduction of area values. Several heating techniques are used for high temperature tensile strength tests and the testing is performed at various de...
متن کاملMetallographic techniques for the determination of the austenite grain size in medium-carbon microalloyed steels
Different techniques have been investigated to seek the best procedure to reveal the prior-austenite grain boundaries in three medium-carbon microalloyed steels. This study has been carried out over a wide range of temperatures (950–1250 C) and it has been found that thermal etching (TE) is the best technique to reveal the prior-austenite grain boundaries in these steels.
