The main role of aluminum titanium boron in aluminum alloy
Grain refinement is one of the important means to improve the strength and plastic toughness of aluminum and aluminum alloy strips, and it is an important way to improve the quality of aluminum.
The cast-rolled strip has a small equiaxed structure, which can make the anisotropy of the product small, uniform deformation during processing, and make the impurities, slag inclusions and the bottom melting point eutectic structure distributed more uniformly on the grain boundary. The strip has good mechanical properties and processing properties.The mechanism of grain refinement: promote nucleation and inhibit grain growth in two ways.
