Example Embodiment
[0033] Example one
[0034] This embodiment is a method for preparing TNM alloy forging blanks with uniform structure.
[0035] The TNM alloy described in this embodiment has a nominal composition of Ti-43Al-4Nb-1Mo-0.2B, the composition is atomic percentage, and the used ingot size is Φ73×99mm.
[0036] The specific process of this embodiment is as follows:
[0037] The first step is to prepare before forging. The ingot to be die-cast is a cylindrical sample, and the surface of the ingot to be die-cast is polished to ensure that its surface quality is good and free of defects. Use ultrasonic flaw detection to confirm that there are no cracks in the ingot, and evenly coat Y on the surface of the ingot 2 O 3 Slurry to avoid oxidation of the surface of the ingot. After the coating is air-dried, the to-be-cast ingot is wrapped. The sheath is composed of a hollow cylindrical sleeve and two end caps. The sheath material is stainless steel with a thickness of 5mm. The inner wall diameter...
