Available in PDF, EPUB and Kindle. Book excerpt: In their bid to produce cast iron latter than Malleable Iron, the scientist discovered the ductile iron or S.G. Iron (spherodial Graphite iron) way back in 1948. The use of this type of cast iron as an engineering material has been increasing day by day ever since its discovery. It is now replacing steel in many important engineering applications. The production of S.G Iron increased to a large extent during last two decades. The excellent combination of mechanical properties obtained in S.G. iron can further be informed by the heat treatment. The most recent development in this regard is the production of Austempered Ductile Iron (ADI). It provides an excellent combination of high tensile strength, wear resistance along with good corrosion resistance and quite significant amount of ductility. Due to these factors, S.G. or ductile iron are austempered when a very favourable combination of various properties is required. But this type of treatment is bit tricky, since it require controlled heating and isothermal holding of the material. So it is necessary to find some attractive methods for property development in S.G. iron. In the present work conventional heat treatment proceeds like annealing, normalizing and tempering of the material has been performed. The mechanical properties obtain by various technique have been compared to one another. In this work two different grades of S.G. Iron (one with copper and another without copper) have been used. The effect of the alloying element (i.e. copper) has also been studied.

Download or read book Microstructure of Steels and Cast Irons written by Madeleine Durand-Charre and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book comprises three parts. Part 1 gives a historical description of the development of ironworking techniques since the earliest times. Part 2 is the core of the book and deals with the metallurgical basis of microstructures, with four main themes: phase diagrams, solidification processes, diffusion, and solid state phase transformations. Part 3 begins by an introduction to steel design principles. It then goes on to consider the different categories of steels, placing emphasis on their specific microstructural features. Finally, a comprehensive reference list includes several hundred pertinent articles and books. The book is the work of a single author, thus ensuring uniformity and concision. It is intended for scientists, metallurgical engineers and senior technicians in research and development laboratories, design offices and quality departments, as well as for teachers and students in universities, technical colleges and other higher education establishments.

Download or read book Effect of Heat Treatment and Tantalum on Microstructure and Mechanical Properties of Fe 9Cr 2W 0 25V Steel written by MA. Sokolov and published by . This book was released on 2004 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Fe-9Cr-2W-0.25V-0.07Ta-0.1C (9Cr-2WVTa) steel has a smaller prior-austenite grain size than this same composition without tantalum (9Cr-2WV) when the steels are given a similar heat treatment. Except for prior-austenite grain size, the microstructures of the steels are similar before irradiation, and they develop similar changes in microstructure during irradiation. Nevertheless, the 9Cr-2WVTa shows less effect of irradiation on the Charpy behavior. To determine the effect of grain size on the Charpy properties of the 9Cr-2WV and 9Cr-2WVTa, specimens of the two steels were given various normalization heat treatments to produce different prior austenite grain sizes, and the tensile and impact properties were determined. For the smaller prior-austenite grain sizes, the 9Cr-2WV steel had impact properties similar to or better than those of the 9Cr-2WVTa steel. Differences in the microstructures of the steels were used to explain the observations and what they mean for developing steels with improved properties.

This book was released on 2014 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of process parameters on the mechanical properties of iso-thermally treated ductile irons was investigated in this study. Sets of ductile irons produced by sandwich method from a rotary furnace melt were given iso-thermal austempering treatments using commercial neutral salt baths. The samples were preheated at 350°C and held for 1 h in a muffle furnace, followed by ausenitizing in an ausenitizing salt bath furnace containing a mixture of BaCl2 and NaCI, (in the ratio 3:2) at 900°C and soaking at that temperature for 1 h. The samples were immediately transferred to the austempering salt bath furnace containing a mixture of NaNO3 and KNO2 in the ratio 1:1. Sets of the samples were soaked at 300°C for between 5 to 240 min and were all later cooled in air. The austempering procedure was repeated at 350 and 400°C for a second and third groups of samples, respectively. The results showed that austempering at lower temperature (300°C) produced a relatively high tensile strength of 1400 MPa, after 150 min holding compared with austempering at the higher temperature (400°C) which produced a relatively lower strength of 1200 MPa at the same holding time. However, the optimal processing window for the austempering was established to be the intermediate temperature of 350°C after a holding time of 150 min. At this processing window, austempering yielded the optimum combination of mechanical properties of 1502 MPa UTS, 7.5 % elongation, and impact energy of 108 J. These properties correspond to a microstructure consisting of a plate-like morphology of ausferrite and retained austenite.
