処することができない場合もある。There is a problem in which the ceramic layer on the surface peels off due to flow or expansion/contraction, and there are also cases where such a ceramic lining cannot solve the problem from the viewpoint of dimensional accuracy.
一方このようなセラミックスライニング等によらず、＾

湯用部材の材料として広く使用することのできないもの
であった。However, all of these materials are moldy when processed, and have problems such as being difficult to process into complex shapes and high dimensional accuracy, and being brittle materials, so they are widely used as materials for parts for molten A1 alloys. It was something that could not be done.

材をかかるＴｉにて構成した場合、溶湯との反応に基づ
く溶損が少なく、Ａ１合金溶湯用部材の耐久寿命を大幅
に延ばすことができる。Ti hardly reacts with A1 alloy, so when a member for molten A1 alloy is made of such Ti, there is less erosion loss due to reaction with the molten metal, and the durability life of the member for molten A1 alloy can be significantly extended. .
またＡ１合金溶湯用部材をＴｉにて構成した場合、コー

工性９寸法績度の点でも特に問題がなく、種々の部材に
対して一般的に適用することが可能である。In addition, when a member for molten A1 alloy is made of Ti, unlike the case of coating, there is no peeling problem, and there is no particular problem in terms of workability and dimensional performance, and it is generally suitable for various parts. It is possible to apply.
本願の別の発明は、かかるＡ１合金溶湯用部材をＴｉ合
