After the casting assembly 5 and the mold are heated to a predetermined temperature, start vacuum induction heating or arc heating for smelting, and set appropriate heating power and smelting time to obtain high-quality alloy melt 3.

[0068] (4) Melt casting: The alloy melt 3 is poured into the casting assembly 5 through the casting port 4, and flows smoothly into the guide port 9 along the channel between the bottom of the baffle 7 and the lower end surface of the casting assembly 5, forming a relatively static melt state to reduce pores and inclusions.

[0069] (5) Preparation of standard sample: The relatively static alloy melt 3 enters the mold cavity 12 of the mold assembly 11 through the guide port 9 and solidifies and forms, and finally obtains a zirconium-based amorphous compression standard sample with excellent performance.

The melt flows along the bottom of the baffle and the lower end surface channel of the casting assembly and enters the guide port to form a relatively static melt state to reduce turbulence and oxidation of the melt during the casting process.

[0077] (5) Standard sample preparation: A relatively static alloy melt enters the mold cavity of the mold assembly through a guide port and solidifies under appropriate cooling conditions to obtain an amorphous alloy die-casting standard sample.

[0081] (2) Assembly of components: The casting component and the mold component are precisely connected through the positioning pins and positioning grooves to ensure the stability and accuracy of the casting process. Subsequently, the entire component is placed under the smelting component, and the resistance heating sleeve of the casting component is turned on, and the heating temperature is set to 900°C; the baffle is set close to the side of the casting port, and the bottom is 5mm away from the lower end face of the casting component; at the same time, the mold resistance heating element is turned on, and the heating temperature is set to 250°C.

The results showed that although the alloy was fully filled, the oxygen content increased to 457 ppm and the compressive strength decreased to 1601.2 MPa, indicating that too high a casting temperature had an adverse effect on the alloy properties.

[0088] Comparative Example 2

[0089] During the alloy melting stage, the resistance heating jacket of the casting assembly was heated to 800° C. The remaining steps were the same as in Example 1. The results showed that although the alloy was fully filled, the oxygen content increased to 268 ppm and the compressive strength decreased to 1578.4 MPa, indicating that too low a casting temperature had an adverse effect on the alloy properties.

[0090] Comparative Example 3

[0092] Comparative Example 4

[0093] During the alloy melting stage, the mold resistance heating element was heated to 100° C. The remaining steps were the same as in Example 1. The results showed that the alloy was not fully filled and could not meet the requirements of the compression standard test, and the oxygen content was 91 ppm, indicating that too low a mold heating temperature had an adverse effect on the alloy properties.

[0094] Comparative Example 5

[0095] Except that the baffle is not provided inside the casting assembly, the remaining steps are the same as those in Example 1. The results show that although the alloy is fully filled, the oxygen content is significantly increased to 463 ppm, and the compressive strength is reduced to 1523.4 MPa.

[0096] Comparative Example 6

[0097] Except that the outer wall of the mold assembly is not provided with a resistance heating element, the remaining steps are the same as those of Example 1. The results show that the alloy is not completely filled and cannot meet the requirements for the compression standard test, and the oxygen content is 92 ppm.

[0098] Comparative Example 7

[0099] At the same time, the baffle inside the casting assembly and the resistance heating element on the outer wall of the mold assembly were removed, and the remaining steps were the same as in Example 1. The results showed that the alloy was not fully filled and could not meet the test requirements, and the oxygen content was as high as 570ppm.

[0100] By comparing the results of the embodiments with the comparative examples, it can be clearly seen that the advantages of the melting and casting device for the zirconium-based amorphous alloy compression standard sample provided by the present invention are: by precisely optimizing the component assembly and heating conditions and the innovative melt casting method, the zirconium-based amorphous alloy is achieved with complete mold filling, low oxygen content and high compressive strength, which provides strong technical support for the wide application of zirconium-based amorphous alloys.
