[0047] like Figure 1-3 shown.
[0048] Taking the preparation of 83Cu-13Al-4Fe alloy powder core wire as an example, the boiling point of Cu is 2562 °C, the boiling point of Al is 2327 °C, and the boiling point of Fe is 2750 °C. It can be seen that the boiling point of Al is the lowest (2327 °C), so the Al element is easy to burn Loss elements (need to increase particle size), and Cu element is selected as the object to reduce particle size.
[0049] Step 1: According to figure 1 The relationship curve between the Cu element powder and the boiling point and melting point, the angle between the tangent of the point on the curve 1 and the nominal boiling point of the element is equal to 5° to distinguish the growth segment and the flat segment, and the corresponding particle size at the junction of the growth segment and the flat segment is 60nm. As the preferred particle size of the Cu element powder (indicated by the vertical dotted line in the figure), then the 60nm partic...

[0059] Taking the preparation of 84Cu-14Al-2Mn alloy powder core wire as an example, the boiling point of Cu is 2562 °C, the boiling point of Al is 2327 °C, and the boiling point of Mn is 1962 °C. It can be seen that the boiling point of Mn is the lowest (1962 °C), so the Mn element is easy to burn Loss elements (need to increase particle size), and Cu element is selected as the object to reduce particle size.
[0060] Step 1: According to the relationship curve between Cu element powder and boiling point and melting point, take the angle between the tangent of the point on the curve and the nominal boiling point of the element equal to 5° as the boundary to distinguish the growth section and the flat section, and select the corresponding point at the junction of the growth section and the flat section. The particle size of 60nm is used as the preferred particle size of Cu element powder, and then the 60nm particle size of Cu powder is used as the benchmark to decrease in order...

[0070] Taking the preparation of 66Fe-14Mn-6Si-9Cr-5Ni alloy powder core wire as an example, the boiling point of Fe is 2750 °C, the boiling point of Mn is 1962 °C, the boiling point of Si is 2355 °C, the boiling point of Cr is 2672 °C, and the boiling point of Ni is 2730 °C , it can be seen that the boiling point of Mn is the lowest, so the Mn element is an element that is easy to burn (need to increase the particle size), and Fe and Ni elements are selected as the objects to reduce the particle size. It should be noted in this example that, considering that the boiling points of Fe element and Ni element are basically the same, it is regarded as an element (defined as Fe / Ni element in this example) for regulation, and considering that the content of Fe element in the wire of this system is It can be used as the outer skin at most, so the mass fraction of Fe powder contained in the powder core can be the same as the Ni element.
