Paper Title:
Grain Refinement Performance of Aluminium Cast-Alloy by Deformed Al-Al3Ti Alloy Refiner
  Abstract

Grain refining experiments for casting of pure Al were conducted to evaluate the grain refinement performance of an Al-5mass%Ti alloy refiner before and after cold rolling. Al3Ti particles in the Al-Ti alloy refiner were efficiently fragmented by cold rolling. The size of the Al3Ti particles in cold rolled Al-Ti alloy refiner decreased from 280μm to 30μm with increasing reduction ratio of cold rolling. Mean size of α-Al grains in pure Al cast refined by the cold rolled Al-Ti alloy refiner decreased from about 500μm to 200μm with increasing the reduction ratio. In order to investigate mechanical property of the pure Al cast refined by the cold rolled Al-Ti alloy refiner, Vickers hardness test and tensile test were conducted. Strength of the pure Al cast refined by the cold rolled Al-Ti alloy refiner increased with increasing the reduction ratio. The strength improvement of pure Al cast refined by the cold rolled Al-Ti alloy refiner followed Hall-Petch relationship. From obtained results, it was concluded that cold rolling for refiner is useful practical application for pure Al cast.
