Abstract

The invention discloses application of amorphous alloy and/or high-entropy alloy to a gong in a minute repeater, wherein the amorphous alloy and the high-entropy alloy have lower elastic modulus, smaller damping on sound, larger and stable amplitude and good anti-relaxation effect, and are used for the gong of the minute repeater so that the time-telling tone quality is clear and crisp.

Description

Application of amorphous alloy and/or high-entropy alloy to gong in three-minute form
Technical Field
The invention relates to the technical field of application of materials, in particular to application of amorphous alloy and/or high-entropy alloy in a gong in a three-questioning table.
Background
The three questions watch, also called as three-spring watch, can distinguish the time, moment and minute according to the different sounds of the three types of striking springs, and is the result of the skillful application of acoustics and dynamics. The sound between three times comes from the hammer to strike the gong, and the whole gong is composed of a metal base connected with two ring gongs, because the two gongs have different lengths, when the hammer strikes, high and low tones with different scales can be emitted, so that the time can be distinguished by hearing. Therefore, the time-telling sound quality becomes a decisive factor for evaluating the quality of the three-question list and also determines the price. The cheap questions in the three questions list may be turbid with sound, and the expensive questions list is clear and limpid with the sound of the sound. At present, the gong is mainly made of a 20AP steel metal rod rich in lead, other elements such as copper can be added according to different requirements such as different timbres, and the preparation process of the gong is complex. European patent No. ep 2107436B 1 discloses that the gong is made of gold in order to have a large number of partials in the sound vibrations generated by the hammer blows. But the gong may be excessively deformed due to its own weight. Since the space inside the watch case where the gong is located is limited, it is susceptible to undesired contact with adjacent parts. This constitutes a drawback of gongs made of gold or any metal with high density and low modulus of elasticity.
The amorphous alloy is prepared by super-quenching solidification, atoms are not in time to be orderly arranged and crystallized when the alloy is solidified, the obtained solid alloy is in a long-range disordered structure, molecules (or atoms and ions) forming the alloy are not in a spatially regular periodicity, and crystal grains and crystal boundaries of crystalline alloy do not exist. Amorphous alloys are considered to be a new generation of structural and functional materials with great application potential due to their unique physical and chemical properties, such as extremely high strength, extremely high elastic strain limit, relatively low young's modulus, good corrosion resistance and wear resistance.
High entropy alloys can generally be defined as alloys of the type in which more than five elemental constituents are alloyed at or near an equiatomic ratio with a mixture entropy above the melting entropy of the alloy, typically forming a high entropy solid solution phase. The main components of the high-entropy alloy are metal elements such as iron, nickel and cobalt, and the elements are the basis of a magnetic material system. The high-entropy alloy has excellent performances such as high strength, high hardness, high wear resistance, high corrosion resistance, high thermal resistance, high resistance and the like which are incomparable with the traditional alloy, so that the high-entropy alloy becomes a new research hotspot after bulk amorphization in the fields of material science and condensed state physics.

The invention discloses application of amorphous alloy and/or high-entropy alloy to a gong in a three-minute form. The amorphous alloy and the high-entropy alloy have lower elastic modulus, smaller damping to sound, larger and stable amplitude, and crisp tone quality. In one embodiment, the invention provides an application of amorphous alloy in a gong of a minute repeater, namely, the gong of the minute repeater is prepared from the amorphous alloy. In another embodiment, the application of the high-entropy alloy in the gong of the minute repeater is provided, namely the high-entropy alloy is adopted to prepare the gong of the minute repeater. In some embodiments, an application of the amorphous alloy and the high-entropy alloy in the gong of the three-minute-scale is provided, namely, the gong of the three-minute-scale is prepared by adopting a mixed material of the amorphous alloy and the high-entropy alloy. Furthermore, the dosage ratio of the amorphous alloy to the high-entropy alloy is 1-5: 1. Particularly, when the using amount of the amorphous alloy is larger than that of the high-entropy alloy, the obtained tone quality is more crisp.
It should be noted that the amorphous alloy in the present application is at least one of a zirconium-based amorphous alloy, a copper-based amorphous alloy, a nickel-based amorphous alloy, a titanium-based amorphous alloy, a tin-based amorphous alloy, or an iron-based amorphous alloy. Preferably, zirconium-based amorphous alloy, copper-based amorphous alloy, titanium-based amorphous alloy are used. For example, the composition of the zirconium based amorphous alloy may be not limited to 30 to 65 wt% of Zr, 20 to 45 wt% of Cu, 6 to 18 wt% of Al, 2 to 13 wt% of Ni, 1 to 6 wt% of Fe, and 1 to 8 wt% of Nb. The composition of the copper-based amorphous alloy may be not limited to containing 35 to 70 wt% of Cu, 10 to 40 wt% of Cr, and 2 to 15 wt% of Al. The Ti-based amorphous alloy may be composed of, but not limited to, 45 to 60 wt% Ti, 20 to 30 wt% Zr, 10 to 20 wt% Cu, 5 to 10 wt% Co, and 1 to 10 wt% Mg. To further illustrate the effect, the inventors prepared sample 1 (Zr)45Cu32Al8Ni6Fe5Nb4) Sample 2 (Cu)60Zr30Al10) Sample 3 (Ti)55Zn22Cu10Co8Mg5) The sizes and the volumes of the samples are the same, a dripping test is carried out in a closed laboratory, the samples 1, 2 and 3 are dripped from the same height, the tone quality crispness performance of the sample 3 is tested to be the best, and then the sample 1 and then the sample 2 are tested. Therefore, the tone quality of the titanium-based amorphous alloy is clearer, and the titanium-based amorphous alloy is preferably the titanium-based amorphous alloy as the gong material of the minute repeater mainly because the strength and the elastic modulus of the titanium-based amorphous alloy are moderate.
