Som en utmärkt högtemperaturmolnlegeringmaterial, TZM (titanium zirconium molybdenum alloy) has gradually become the first choice of engineers due to its unique performance advantages in the competition with traditional tungsten and pure molybdenum materials. TZM alloy is mainly composed of molybdenum (Mo) as the matrix, with about 0.50% titanium (Ti) and 0 . 08% zirkonium (zr) och en liten mängd kol (c) tillsatt. Detta noggrant designade legeringssystem ger TZM-legering en serie utmärkta egenskaper, vilket gör att den lyfter i fältet högtemperatur.
1. Smältpunkt och hög temperaturstabilitet
(I) Jämförelse av smältpunkter av TZM, volfram och ren molybden
Tungsten has an extremely high melting point of about 3422℃. The melting point of pure molybdenum is also quite high, at about 2610℃, while the melting point of TZM alloy is around 2617℃. From the melting point value, although the melting point of TZM is slightly lower than that of tungsten, it is close to that of pure Molybdenum . Men i faktiska extrema höga temperaturapplikationer är smältpunkten inte den enda överväganden .
(Ii) Analys av hög temperaturstabilitet
TZM alloy exhibits excellent stability at high temperatures. Its recrystallization temperature is as high as about 1400℃, which is significantly higher than that of pure molybdenum. Excessively high recrystallization temperature means that TZM can maintain its original structure and performance for a longer time in a high-temperature environment, effectively reducing the risk of material performance degradation caused by recrystallization. In contrast, pure molybdenum is more likely to recrystallize at high temperatures, making its high-temperature stability inferior to that of TZM. Although tungsten has an extremely high melting point, it is easy to react with oxygen in certain high-temperature oxidizing environments, resulting in a decrease in material prestanda .
2. Mekanisk prestanda
(I) styrka och hårdhet
At room temperature, TZM alloy exhibits higher strength and hardness than pure molybdenum. When the temperature rises to an extreme high temperature environment of 1000℃and above, the tensile strength of TZM can reach 700-720MPa, while pure molybdenum is only about 223MPa. This good strength retention ability at high temperatures makes TZM perform well in applications that withstand high temperature loads, such as rocket engine nozzles and high-temperature furnace structural components. Although tungsten has extremely high hardness, it is brittle. In some application scenarios where the material needs to have a certain toughness, TZM has more advantages.
(Ii) krypmotstånd
Creep resistance is an important indicator to measure the ability of a material to resist deformation under high temperature and long-term load. Its unique alloy composition and microstructure make TZM's creep resistance at high temperature far superior to pure molybdenum. In high temperature and high pressure environments, such as high temperature components of aircraft engines, hot extrusion dies, and other applications, TZM's Krypmotstånd kan säkerställa att komponenterna upprätthåller en stabil form och dimensionell noggrannhet under långvarig användning, vilket kraftigt förbättrar utrustningen och livslängden för utrustningen .
3. Termisk och elektrisk konduktivitet
(I) Termisk konduktivitet
The thermal conductivity of TZM alloy is similar to that of pure molybdenum, which is about 126W/(m·K) at room temperature. This good thermal conductivity makes TZM widely used in equipment that requires efficient heat dissipation, such as electron tube radiators and high-temperature heat exchangers. Compared with tungsten, TZM can achieve heat transfer more quickly and maintain the stabil drift av utrustningen .
(Ii) elektrisk konduktivitet
The resistivity of TZM alloy is about (5.3 - 5.5)×10⁻⁸Ω·m. In some high-temperature electrical applications that require electrical conductivity, such as the gate in electron tubes and high-voltage rectifier components, TZM can meet the electrical conductivity requirements, and at the same time, with its good high-temperature performance, it ensures stable operation in Miljöer med hög temperatur .
4. Bearbetning och svetsprestanda
(I) Behandlingsprestanda
TZM -legering har god bearbetningsprestanda och kan bearbetas med konventionella kalla bearbetningsmetoder . I närvaro av kylande smörjolja kan karbidverktyg användas för bearbetning, vilket gör att TZM har hög genomförbarhet och bearbetning av noggrannhet när man tillverkar delar med komplexa former .}
(Ii) Svetsprestanda
TZM alloy has good welding performance and can be well welded with a variety of materials. This feature enables TZM to achieve efficient assembly through the welding process when manufacturing large structural parts or high-temperature equipment that needs to combine different materials, greatly improving production efficiency and overall product performance. The welding of pure molybdenum is relatively complex and requires special welding processes and conditions För att säkerställa svetskvalitet .
5. Kostnadseffektivitetsanalys
Även om priset på TZM-legering är cirka 25% högre än det för ren molybden, efter att ha omfattande med tanke på dess prestandafördelar och applikationseffekter, har TZM högre kostnadseffektivitet . i extremt höga temperaturmiljöer, TZM: s långa livslängd, höga tillförlitlighet och goda processer och svetsprestanda kan effektivt minska utrustningskostnaderna, minska tidens underhåll och minska tidpunkten och minska tidpunkten och minska tidpunkten och förbättra tidpunkten och förbättra tidpunkten)
