The preparation process of TZM alloy rod has an important influence on its material properties. The influence of several preparation process factors on the performance of TZM alloy rods is listed below:
Alloy composition control: When preparing TZM alloy rods, precise control of the ratio of elements such as molybdenum (Mo), titanium (Ti) and zirconium (Zr) is crucial to the final material properties. The change of alloy composition will directly affect the high temperature strength, corrosion resistance, thermal fatigue resistance and other properties of TZM alloy rod.
Sintering process: The sintering process of TZM alloy rod has an important influence on the density, grain size and structure of the material. Appropriate sintering temperature and time can achieve the densification of the alloy and promote the growth and orientation of the grains, thereby improving the strength and mechanical properties of the material.
Heat treatment process: Through different heat treatment processes, such as annealing, solution treatment and aging treatment, the microstructure and properties of TZM alloy rods can be further adjusted. Proper heat treatment can eliminate internal stress, improve the toughness and plasticity of the material, and optimize the grain structure, thereby improving the high temperature stability and durability of the material.
Processing technology: The processing technology also has an important influence on the ultimate performance of TZM alloy rods. For example, through forging, stretching, spinning and other processing methods, the mechanical properties of the material can be improved, and the uniformity and compactness of the material can be improved, thereby enhancing the strength and reliability of the TZM alloy rod.
