Determination of Ms temperature: Methods, meaning and influence of 'slow start' phenomenon
A Study on Graphitization Acceleration during Annealing of Martensitic Hypereutectoid Steel
In the present experimental study, the influence of primary martensitic structure on acceleration of graphitization process in hypereutectoid steels during subsequent heat treatment cycle was investigated by using of optical microscopy (OM...
Thermal stability of retained austenite in Cr Ni weld metals at low temperatures
Effect of recalescence on microstructure and phase transformation in high carbon steel
A Novel Process on Production of Thin Wall Austempered Ductile Iron Heat-treated in the Mold
were examined by optical microscopy. Results indicated that the ausferrite microstructure can be achieved by the control of the cooling rate within temperature range between 280-400°C. Austempering time about 1hr resulted in no trace of martensite...
Effect of Austenitizing Temperature on the Micro-structure of Ductile Irons Containing 2% Al
Considering the importance of austenization in preparing steel, it is crucial to have a good understanding of the effects of temperature on this process. In this project, we studied these effects on an aluminum-containing ...
Effect of Martensite Structure in Graphitization Process in Hypereutectoid Steel
Graphitization process in steel is referred to the decomposition of meta-stable cementite phase to more stable phases of graphite and ferrite. I n steels this transformation often occurs in the range of 600-700°C. In common ...
The Effect of Cooling Rate on Bainite Phase Formation in Austempered Nickel-Molybdenum Gray Cast Iron
. The results indicated that, by increasing the cross sections of samples, the martensite percentage decreases and the phase proportion of bainitic ferrite increases....
