Abstract

Apabila penukleusan telah lengkap, proses pemejalan seterusnya melibatkan pertumbuhan nukleus. Pertambahan kadar pertumbuhan akan mengecilkan saiz bijian logam. Oleh itu, kajian ke atas parameter–parameter tuangan yang memberi kesan ke atas kadar pertumbuhan perlu dilakukan bagi memperbaiki sifat mekanik logam. Kertas kerja ini dengan itu mencadangkan suatu persamaan kadar pertumbuhan antara muka logam pepejal dalam keadaan lebur yang dituangkan daripada suatu tundish bergerak ke dalam suatu acuan condong. Persamaan yang dicadangkan boleh digunakan secara praktik dan parameter–parameternya boleh ditentukan secara ujikaji. Kata kunci: Pemejalan logam; tuangan; penukleusan; pertumbuhan bijian When nucleation is completed, the solidification process will continue with nucleus growth. Increasing the growth rate will reduce the grsin size of metal. Thus the study on the casting parameters which have an effect on the growth rate should be carried out in order to improve the mechanical properties of the metal. This work thus propose an equation of growth rate of solidified metal interface in the molten state which is poured from a moving tundish into an inclined mould. The proposed equation can be practically applied and the parameters can be experimentally determined. Keywords: Solidification; casting; nucleation; grain growth
