  • Austempering of Spheroidal Cast Iron. 

    Onuoha, Enyinnaya Martin (Obafemi Awolowo University, 1986)
    The effect of austempering on the hardness, ultimate tensile strength and per cent elongation of twenty pre-annealed unalloyed spheriodal cast iron specimens have been investigated and evaluated. The specimens were solution ...
  • Effects of Microstructures on the Thermal Properties of Refractory Materials. 

    Adeoye, Mosobalaje Oyebamiji (Obafemi Awolowo University, 1986)
    The factors controlling the thermal properties of refractory clays obtained from Omi-Adio were investigated. Methods of controlling these factors in refractory bricks were also looked into. A complete feasible step in ...
  • Effect of Composition on the Dielectric Properties of Electrical Porcelain. 

    Akinbami, John-Fekix Kayode (Obafemi Awolowo University, 1987)
    The effect of compositional change on the dielectric properties (i.e. dielectric constant, dielectric resistance, dissipation factor, loss factor) of Electrical Porcelain has been investigated. The evaluation was carried ...
