The Effects of Cr and Al Addition on Transformation and Properties in Low-Carbon Bainitic Steels
Three low-carbon bainitic steels were designed to investigate the effects of Cr and Al addition on bainitic transformation, microstructures, and properties by metallographic method and dilatometry. The results show that compared with the base steel without Cr and Al addition, only Cr addition is effective for improving the strength of low-carbon bainitic steel by increasing the amount of bainit...
متن کاملQuasi-Static and Dynanmic Deformation Behaviors of Medium-Carbon Steels in a Wide Temperature Range
This paper presents a study of the quasi-static and dynamic deformation behaviors of conventional and microalloyed medium-carbon steels in a wide temperature range. As strain rate increased, the flow stress increased at room temperature, but occasionally did not at elevated temperatures. The flow stress of the microalloyed steel containing precipitates was less sensitive to strain rate at room ...
متن کاملAnalysis of Abrasive Wear Characterization and its Correlation with Structure for Low and Medium Carbon Steels
In most of the engineering applications, such as mining, metallurgy, agriculture; equipments are failed by the abrasive wear. The data as obtained form ministry of Research and Technology indicates that the percentage cost of abrasive wear in federal republic of German in metallurgy industry is 40%, mining industry 30%, agriculture 20% and production engineering 10%, and so the material selecti...
متن کاملUranium-mediated oxidative addition and reductive elimination.
Oxidative addition, and its reverse reaction reductive elimination, constitute two key reactions that underpin organometallic chemistry and catalysis. Although these reactions have been known for decades in main group and transition metal systems, they are exceptionally rare or unknown for the f-block. However, in recent years much progress has been made. In this Perspective article, advances i...
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.
