  • Vermicular cast iron alloy for internal combustion engine block and head
    Patent number: 11434552
    Abstract: The present invention refers to a vermicular cast iron alloy specially designed for internal combustion engine blocks and heads having special requirements of mechanical strength and fatigue strength. Vermicular iron alloy with high mechanical strength and high fatigue strength for the production of internal combustion engines blocks and heads characterized by having a microstructure of pearlitic matrix and predominantly vermicular graphite (>70%) and presence of graphite nodules in up to 30%, wherein its graphite microstructure is described by the Microstructure Factor (FM), as defined below, with Microstructure Factor values higher than 0.94.

  • Vermicular Cast Iron Alloy, Combustion Engine Block and Head
    Publication number: 20220090238
    Abstract: The present invention refers to a vermicular cast iron alloy specially designed for blocks and heads of internal combustion engines that have special requirements for mechanical strength and machinability; said vermicular alloy has a microstructure that results in high values of mechanical properties, such as a minimum strength limit of 500 Mpa, a minimum yield limit of 350 MPa, along with good machinability; also, wherein the ferritization factor must be such that it is between 3.88 and 5.48. This set of properties makes it possible to design new engine blocks and heads with complex geometry, high mechanical properties, without compromising machinability, making it attractive both from a technical and economic point of view.
