Embodiment 1

[0103] The alloy of the present invention will be described based on specific examples.

[0104] Samples containing 10 types of alloys listed in Table 2 were prepared. Alloys No. 34 to No. 40 of Examples were produced by arc melting under the following conditions. In addition, as a comparative example, a sample (No. 31) including JIS SKD61, a sample (No. 32) obtained by nitriding the surface of JIS SKD61, and a NbTaTi alloy (No. 33) were prepared. About JIS SKD61, it manufactured with the composition and manufacturing method based on JIS G4404, About NbTaTi alloy (No. 33), it manufactured similarly to an Example.

[0105] In the alloy of the embodiment of Table 2, the content of the constituent elements of No.34 to No.36 is the same amount, the four constituent elements (Nb, Mo, Ta, W) of No.40 are the same amount, and the other elements are 2 times the equivalent amount. In addition, alloys No. 37 to No. 39 have compositions obtained by simulating combinations of elements ...

[0175] Hereinafter, application examples of the alloy of the present invention will be specifically described. In addition, the components of the present invention are not limited to the use of these examples.

[0176]

[0177] Various starting materials shown in Table 9 were prepared. The raw material powders are all pure metal powders obtained by chemical reduction. These raw materials were weighed so that they became samples of No. 41 to No. 44 shown in Table 10, and mixed for 30 minutes with a V mixer, whereby a plurality of powders with different specific gravity in each raw material powder were mixed. The ingredients are mixed evenly. The composition of Table 10 is at %.

Abstract

Provided is an alloy having resistance to an aluminum alloy or the like in a molten state. The alloy contains Nb and Mo as a first element group and at least one of Ta, W, Ti, Hf and Zr as a second element group, and when the total of the elements of the first element group and the second element group is 100 at.%, the content range of the contained elements is 5 at.% to 35 at.%, and the lattice mismatch of the alloy with respect to at least one of Al, Cu and Zn is 13% or more. And has tolerance such that the migration barrier energy of dislocation is 310 kJ / mol or more.

Description

technical field [0001] The present invention relates to an alloy having resistance to an alloy in a molten state or a plastic state, especially an aluminum alloy, and a member using the alloy. Background technique [0002] Dies used in low-pressure casting, gravity casting, and die-casting of aluminum alloys are, for example, Japanese Industrial Standards (JIS) SKD61. When casting is repeated using the same mold, the mold will be damaged. The main cause of damage is melting loss. Melting loss occurs due to the lowering of the melting point due to partial alloying of the mold in contact with the molten aluminum alloy. [0003] When the melting loss intensifies, repair the melted part by welding and surfacing. As the repairing material, an alloy having a high melting point and excellent creep resistance at high temperature and corrosion resistance is preferable. An example of such an alloy is disclosed in Patent Document 1. [0004] In the case of requiring high strength ...
