Embodiment 1
[0017] Take 29.7g of pure zirconium wire, 29.7g of pure titanium wire, and 0.6g of pure nickel wire, and place them in a non-consumable vacuum arc melting furnace for repeated melting for 6 times, each melting time is 3 minutes, and the melting electrode current is kept at 190-220A After each smelting is completed, wait for the ingot to cool to room temperature, and then perform the next smelting to obtain a zirconium-titanium-nickel alloy ingot with uniform composition. The smelted alloy ingot is cooled in the smelting furnace for 10 minutes and then taken out. Such as figure 1 As shown, it can be known that the phase composition of the prepared zirconium-titanium-nickel alloy is α phase and trace amount of C14 phase. Such as figure 2 As shown, it can be seen that the microstructure of the prepared zirconium-titanium-nickel alloy is composed of flaky α phase. Such as Figure 5 It shows that the prepared zirconium-titanium-nickel alloy has good fracture strength and high ...
Embodiment 2
[0020] Take 29.1g of pure zirconium wire, 29.1g of pure titanium wire, and 1.8g of pure nickel wire, and place them in a non-consumable vacuum arc melting furnace for repeated melting for 6 times, each melting time is 3 minutes, and the melting electrode current is kept at 190-220A After each smelting is completed, wait for the ingot to cool to room temperature, and then perform the next smelting to obtain a zirconium-titanium-nickel alloy ingot with uniform composition. The smelted alloy ingot is cooled in the smelting furnace for 10 minutes and then taken out. Such as figure 1 As shown, it can be known that the prepared zirconium-titanium-nickel alloy contains α phase and trace amount of C14 phase. Such as image 3 As shown, it can be seen that the microstructure of the alloy is composed of flaky α-phase, but the width of the α-sheet layer is reduced compared with the zirconium-titanium-nickel alloy prepared in Example 1, indicating that the increase of nickel will make th...
Embodiment 3
[0023] Take 28.5g of pure zirconium wire, 28.5g of pure titanium wire, and 3g of pure nickel wire, and place them in a non-consumable vacuum arc melting furnace for repeated melting 6 times, each melting time is 3 minutes, and the melting electrode current is kept at 190-220A. After each smelting is completed, wait for the ingot to cool down to room temperature, and then perform the next smelting to obtain a zirconium-titanium-nickel alloy ingot with uniform composition. The smelted alloy ingot is cooled in the smelting furnace for 10 minutes and then taken out. Such as figure 1 As shown, it shows that with the increase of nickel content, the content of C14 phase in the alloy increases. The prepared zirconium-titanium-nickel alloy consists of two phases: α phase and C14 phase. Such as Figure 4 As shown, it shows that the metallographic microstructure of the prepared zirconium-titanium-nickel alloy is composed of flaky α phase and C14 compound. Such as Figure 5 As shown,...
