High-temperature alloy for electronic firework push rod as well as preparation process and application of high-temperature alloy

Abstract

The invention provides a high-temperature alloy for an electronic firework push rod and a preparation process and application of the high-temperature alloy. The high-temperature alloy comprises the following chemical components in percentage by mass: 23-25% of Cr, not more than 1.0% of Fe, 3.15-4.15% of Nb, 10.0-12.0% of Mo, 1.0-2.0% of Co, not more than 0.06% of C, not more than 0.5% of Mn, not more than 0.5% of Si, not more than 0.015% of S, not more than 0.015% of P, not more than 0.07% of Cu, not more than 0.4% of Al, not more than 0.4% of Ti and the balance of Ni. The high-temperature alloy for the electronic firework push rod solves the problems of poor high-temperature mechanical property and short service life of the high-temperature alloy in the prior art, has good thermal stability and mechanical property at room temperature and 1100 DEG C, and can be used for the electronic firework push rod.

Description

Technical field [0001] The present invention relates to the field of nickel-based high-temperature alloys, and more particularly to a high temperature alloy for electronic fireworks and its preparation processes and applications. Background technique [0002] Under the national ban on fireworks and firecrackers, the fireworks fireworks firecrackers have an extremely large blank market, while electronic fireworks are excellent alternative products. Electronic fireworks belong to environmentally friendly fireworks, and the discharge process does not produce toxic and harmful gases and will not pollute the environment. [0003] Electronic fireworks are generally made of cold flame, using a lower metal powder with a combustion point, a cold light smokeless firework, a cold light smokeless firework, a cold flame full of fire, only 30 ~ 50 ° C, the external temperature is not harmful to the human body, suitable for Stage performances and various styles design. [0004] Although the col...
