inoculation of primary austenite in Grey Cast Iron
International Journal of Cast Metals Research, 2007Co-Authors: Attila Dioszegi, Kalle Z Liu, Ingva L SvenssoAbstract:AbstractPrimary austenite is the least investigated microstructural component of Grey Cast Iron. It is the first phase to be nucleated in the liquid metal and it grows in a dendritic manner, followed by growth of the eutectic phase. This paper describes an investigation on three potential nucleating agents to promote the nucleation of primary austenite in Grey Cast Iron under industrial conditions. A direct austempering after solidification (DAAS technique) was used to determine the number of primary austenite grains. A colour etching technique was used to reveal the primary austenite grains and the eutectic cells. The results show that properly chosen nucleation agents significantly promote the number of primary austenite grains. Furthermore, the authors show that the eutectic cell size and the morphology of the graphite are obviously influenced by the primary solidification in Grey Cast Iron. The increased nucleation of austenite grains resulted in an increased number of eutectic cells.

Effect of Cu and Mo addition on mechanical properties and microstructure of Grey Cast Iron: An overview
Materials Today: Proceedings, 2020Co-Authors: Shantanu Upadhyay, Kuldeep K. SaxenaAbstract:Abstract The addition of any alloying element alters the various properties of developed alloy, wherein mechanical properties influence significantly. The present work reviews the effect of molybdenum (Mo) and copper (Cu) addition in Grey Cast Iron. It alters the few mechanical properties such as tensile strength, hardness and toughness of Grey Cast Iron and are covered in this review article. It is reported that on increasing the percentage of copper and molybdenum in Grey Cast Iron, tensile strength and hardness increases and impact energy decreases. But, beyond a certain amount of copper and molybdenum addition, there is a negligible effect on the hardness. Thus the main role of copper and molybdenum addition, is to reduce the volume of graphite flakes and increase the content of pearlite in microstructure of gray Cast Iron.

Effect of niobium addition in Grey Cast Iron: A short review
Materials Today: Proceedings, 2020Co-Authors: Gaurav Beniwal, Kuldeep K. SaxenaAbstract:Abstract The effect of alloying element addition in Grey Cast Iron is great interest of materials developers. In the same context, the effect of adding niobium on mechanical properties of Grey Cast Iron is reviewed. Microstructure and hardness test are reviewed to examine the mechanical properties of alloyed Grey Cast Iron. The study indicated that increasing niobium results in increasing hardness due to which wear rate reduces and also reduces the lamellar spacing between the graphite layers. The reduction in lamellar spacing is due to decreases in eutectic temperature with the addition of niobium. Additionally, mechanical properties including hardness and wear resistance were enhanced after adding niobium.

Influence of S and Mn on mechanical properties and microstructure of Grey Cast Iron: An overview
Materials Today: Proceedings, 2020Co-Authors: Raghav Srivastava, Bharat Singh, Kuldeep K. SaxenaAbstract:Abstract In the present review article, influence of S and Mn on microstructure and mechanical properties is studied. Additionally, effect of manganese and sulfur on the wear property of Grey Cast Iron was also reviewed. The data from different experiments were taken under consideration and studied for the examination of the alloyed Cast Iron. The study describes that on increasing the manganese content of the Grey Cast Iron, wear coefficient and hardness decreases and impact energy increases. The main motive of addition of manganese is to control the adverse effect of sulfur on the mechanical properties of Grey Cast Iron. Moreover, the presence of manganese counter the formation of FeS, which is the reason for hot shortness in the alloy.

Effect of silicon addition on microstructure and mechanical properties of Grey Cast Iron: An overview
Materials Today: Proceedings, 2020Co-Authors: Prachi Singhal, Kuldeep K. SaxenaAbstract:Abstract Grey Cast Iron is used to make brake disc due to its high damping vibration resistance and low cost. In the present work, effect of silicon addition on microstructure and mechanical properties of Grey Cast Iron is reviewed. Results of microstructure and mechanical properties are compiled, which are affected due to the addition of silicon in Grey Cast Iron. From the review, it is found that the volume of soft graphite flakes increases i.e. grain size increases which reduces the hardness of Grey Cast Iron, on increasing the silicon content. Similarly, tensile strength reduces as a function of silicon addition. Hardness and wear rate depends on the phase of microstructure and the size of graphite flakes. Maximum hardness was obtained at 3.33% of silicon content.

Fatigue Strength of Machined and Shot Peened Grey Cast Iron
Advanced Materials Research, 2014Co-Authors: Mattias Lundberg, Maqsood Ahmad, Ru Lin Peng, Daniel Bäckström, Taina Vuoristo, Sten JohanssonAbstract:A common opinion is that Cast Iron, especially Grey Cast Iron, is not as notch sensitive as steel and has therefore not been treated by shot peening to suppress crack initiation. For a heterogeneous material that also is brittle, just like Grey Cast Iron, the shot peening parameters needed to induce beneficial surface residual stresses can be problematic to identify. Fatigue testing under uniaxial loading with an R value of -1, on mechanically polished and shot peened specimens, has been performed to determine the fatigue strength at 107 cycles as well as complete Wohler-curves. Two different types of specimen geometries were tested, one smooth and one notched specimen having kt equal to 1.05 resp. 1.33. With large shots and high peening intensity (heavy SP) the fatigue strength clearly decreased whereas small shots and low peening intensity (gentle SP) might have lowered the fatigue strength. A short annealing at 285° after gentle shot peening increased the fatigue strength. The results are discussed and explained based on x-ray diffraction (XRD) measurements, i.e. residual stress and full width at half maximum profiles, as well as microstructural investigations using scanning electron microscope (SEM).
