Abstract
Cast iron powders containing little amount of Al, Cr, and Si were produced via water atomization technique and then got annealed at 900 °C for removing oxygen in hydrogen atmosphere. The advantages of rapid solidification remained undisturbed in spite of high temperature. The powders after pre-compaction studies were cold compacted up to 700 MPa pressure and then sintered at different temperatures like 720, 850, and 1000 °C. Growth like dimensional changes was observed in all the samples. The sample which was compacted at 700 MPa and sintered at 1000 °C showed 48 HRC hardness. High hardness values could enable these materials for manufacturing high-strength machine components.
