抄録

Effects of TiB₂ and TiAl₃ particles, smaller than 15μ and 600μ, respectively, on grain refining of cast structure of 99.75% and 99.99% aluminum were studied. The results obtained are as follows:<br>1) Grain size of cast aluminum decreased when 0.01 to 0.10%TiB₂ was added. This effect became more pronounced as the particle size decreased. Further, it was found that the refinement effect due to TiB₂ was more effective when the temperature of molten aluminum was raised to 900°C and 0.006%Ti was added in advance.<br>2) Similarly, grain refining effect due to TiAl₃ became more pronounced as the content of TiAl₃ increased from 0.07% to 0.54% and the particle diameter decreased. This effect was further noted when the holding time and the temperature of the molten metal containing TiAl₃ particles increased.<br>3) When 0.05%TiB₂ and 0.016%TiAl₃ were added together to the molten metals, the refinement effect was very pronounced if the particle sizes of TiB₂ and of TiAl₃ were less than 2μ and 100μ, respectively. This observation was consistent with the refinement effect of the Al-5%Ti-1%B master alloy on the cast structure of pure aluminum.
