Description of the Related Art Al-Ti alloys are used as a master alloy for adding titanium (Ti) for the purpose of miniaturizing a metal structure in an aluminum alloy casting, or as a sputtering target for forming a deposited film. It is used and is attracting attention as a lightweight structural material with high strength, high elasticity and high temperature strength. On the other hand, since the range between the solidification start temperature and the solidification end temperature is considerably large at several hundred K in the Al-Ti alloy, the aluminum titanate (Al 3 Ti) structure tends to grow coarsely in the solidification process. Many nests,
The production yield of cast products was poor. In addition, in order to crush the shrinkage cavities, it takes time to perform hot plastic working on the cast product, and furthermore, the presence of a coarse Al 3 Ti structure tends to cause cracking of the product during plastic working. ,
Reheating-reworking had to be repeated several times.

The effect on the refinement of the Ti structure became remarkable, and the refinement of the Al 3 Ti structure tended to progress as the composition amount increased. However, when the carbon content is 1.0 wt% or more, aluminum carbide (Al 4 C 3 ) is generated, so that it is not preferable to make the carbon content 1.0 wt% or more.

3 The number and length per unit area of Ti is indicative of the fineness of the metal structure in the Al-Ti-C alloy. The result is shown in FIG. From this measurement result, it was found that the number of Al 3 Ti per unit area increased, but the length of the Al 3 Ti crystal became shorter as the carbon composition amount increased.

The reaction product between the i-based alloy and carbon (C) varies depending on the temperature and the titanium content, and as shown in Table 1 below,
When the temperature is high (1273K), the temperature is low (973K) when the titanium composition is small (0.5wt%).
In this case, aluminum carbide (Al 4 C 3 ) is generated when the titanium composition is relatively large (4.3 wt%). At a temperature of 1173 K or higher, aluminum carbide (Al 4 C 3 ) is used when the titanium composition is less than 2.0 wt%.
Is generated, and titanium carbide (TiC) is generated when the titanium composition amount is 2.0 wt% or more. Among them, aluminum carbide (Al 4 C 3 ) has deliquescence and is inconvenient as an industrial material, but titanium carbide (TiC) is effective.

Reacts to form titanium carbide (TiC),
The weight ratio is such that carbon (C) is 4 with respect to titanium (Ti) 1.
Therefore, the residual titanium composition amount (wt%) of the molten Al—Ti alloy is a value obtained by subtracting the carbon composition amount (wt%) four times from the titanium composition amount (wt%). On the other hand, Al
In a verification example of a Ti-5C-based alloy of -5 wt%, when the carbon content becomes 1.0 wt% or more, aluminum carbide (Al 4

The titanium composition (wt%) obtained by subtracting twice the carbon composition (wt%) becomes 1.96 wt% when the carbon composition is 0.76 wt%, and becomes 1.096 wt% when the carbon composition is 1.0 wt%. Is 1.0 wt%, so the lower limit composition amount of titanium was 1.6 wt%.
