Paper Title:
Effect of Ni on Characteristics and Structure of Aluminium Brass
  Abstract

Studying effects of Ni content (0.6%, 0.8% and 1.0%) on structure and properties of aluminum brass (Cu-22.7Zn-3.0Al) as-cast ingot, cold-rolled and annealed sheet. The results show that: Ni can restrain the precipitation of β phase, and increase percentage of α phase during casting process. The proportion of α phase of ingot as-cast grows up with the increase of Ni content in the alloy. α phase refines gradually and shape changes to needle-like and distributes more uniform with the increase of Ni. The average grain size of α phase of ingot as-cast is 33.57μm, 31.78μm and 28.32μm respectively, and the percentage of α phase as-cast is 69.73%, 75.18% and 78.91% corresponding to 0.6%, 0.8% and 1.0% Ni respectively in the alloy. The tensile strength and hardness enhance and elongation drops with the increase of Ni content. The hardness, tensile strength and elongation is 238.7HV, 784.9MPa and 3.7% respectively for 0.2mm thickness cold-rolled sheet with 1.0% Ni in the alloy. The sheet from 1.0mm to 0.2mm thickness undergoes deformation and heat-treatment process. The hardness and tensile strength of cold-rolled strip of 0.2mm thickness are 205HV and 691.16MPa that increase 13.25% and 16.45% than cold-rolled sheet of 1.0mm thickness.
