The processing technology of UNS N06025 high temperature alloy generally includes two methods: hot working and cold working. Hot processing includes hot forging and hot rolling, which can improve the high-temperature strength and plasticity of the alloy. Cold working is used to improve the strength and corrosion resistance of the alloy. The alloy has good heat treatment properties and its properties can be optimized through solution treatment and aging treatment. Solid solution treatment can eliminate the precipitation phase of the alloy and improve its hardness and strength, while aging treatment can further improve the strength and corrosion resistance of the alloy. The following will introduce in detail the processing technology and heat treatment properties of UNS N06025 high temperature alloy.
Processing technology of UNS N06025 alloy:
Temperature control: The processing temperature of the alloy must be controlled within an appropriate range to avoid overheating, which may lead to grain growth and a decrease in material strength.
Processing intensity: Processing intensity should be adjusted according to the hardness and ductility of the alloy to avoid deformation or cracking caused by excessive stress.
Cutting fluid: Using appropriate cutting fluid during cutting can improve processing efficiency and reduce tool wear.
Heat treatment properties: The heat treatment of UNS N06025 superalloy has an important impact on its mechanical properties and microstructure. Common heat treatment methods include solution treatment and aging treatment.
Solid solution treatment: heating the alloy to an appropriate temperature to uniformly disperse the elements in the solid solution phase into the matrix and improve the mechanical properties and corrosion resistance of the alloy. The solid solution temperature is generally in the range of 980℃-1100℃, and the solid solution time is determined according to the specific requirements.
Cooling method: After solution treatment, the alloy needs to be cooled quickly to avoid recrystallization. Commonly used cooling methods include water quenching, oil quenching and air cooling.
Aging treatment: After solution treatment, the alloy is kept at an appropriate temperature for a period of time to promote the formation of precipitation hardening phases and strengthen the mechanical properties of the material. The aging temperature is usually between 480℃-760℃, and the aging time is determined according to specific requirements.
