Related production processes:
- Alloy Preparation: The base alloy composition of GH2136 is prepared by melting and alloying various metallic elements. This is typically done through methods such as vacuum induction melting (VIM) or electron beam melting (EBM). The alloy composition is carefully controlled to ensure the desired properties of the material.
- Ingot Casting: The molten alloy is then cast into ingots using processes like vacuum arc remelting (VAR) or directional solidification. Ingot casting helps achieve a desirable microstructure and uniform composition in the material.
- Hot Working: The cast ingots are then subjected to hot working processes such as forging, rolling, or extrusion. These processes involve applying heat and mechanical force to shape the material into desired forms like bars, plates, or billets. Hot working helps refine the microstructure, improve mechanical properties, and enhance the material's uniformity.
- Heat Treatment: GH2136 filament material often undergoes heat treatment to optimize its properties. This typically involves processes like solution treatment, which involves heating the material to a specific temperature range and then cooling it rapidly or slowly to achieve the desired microstructure and mechanical properties.
