What Is The Appropriate Ratio For High-temperature Alloy Forging? Learn About This Article In Three Minutes [recommended Throughout The Internet]

What is the suitable forging ratio for high temperature alloys? High temperature alloy> Due to its excellent high temperature strength, oxidation resistance and corrosion resistance, it is widely used in the aerospace, energy and chemical industries. Forging is one of the important processes in high-temperature alloy processing, and the choice of forging ratio directly affects the structural performance of the material and the quality of the final product. So, what is the forging ratio of high-temperature alloys? Let's take a look at the editor.

1. Definition of forging ratio

Forging ratio refers to the ratio of the cross-sectional area before and after metal deformation during forging, which is usually expressed by the formula:

Forging ratio = initial cross-sectional area/final cross-sectional area

The forging ratio reflects the degree of deformation of the metal and is an important parameter for measuring the forging process.

2. Selection range of high temperature alloy forging ratio

The forging ratio of high temperature alloys is usually between 2:1 and 6:1 CNC part, and the specific choice depends on the following factors:

Alloy type: Different components of high-temperature alloys have different sensitivity to forging ratios. For example, nickel-based high-temperature alloys usually require higher forging ratios (4:1 to 6:1), while iron or cobalt-based high-temperature alloys have slightly lower forging ratios (2:1 to 4:1).

Product usage: For high performance fields, such as aerospace, a higher forging ratio is usually chosen to ensure the density and uniformity of the material; although for general industrial purposes, the forging ratio can be appropriately reduced.

Process conditions: Forging temperature, deformation rate and equipment capability will also affect the choice of forging ratio.

3. Effect of forging ratio on the performance of high-temperature alloys

Tissue Improvement: Higher forging ratios can effectively improve grains and improve material strength and toughness.

Eliminate defects: With enough deformation, defects such as pores and shrinkage can be eliminated and the compactness of the material can be improved.

Performance uniformity: Appropriate forging ratios can improve the anisotropy of the material and make the performance more uniform.

4. Things to pay attention to when choosing forging

Avoid excessive forging ratios: Excessive forging ratios can cause excessive stress to the material or even cracks.

Step-by-step forging: For high-temperature alloys that require large deformation, multiple characters (step-by-step forging) can be used to gradually achieve the target forging ratio to avoid excessive deformation at one time.

Temperature control: The forging temperature range of high-temperature alloys is relatively narrow, and the forging temperature needs to be strictly controlled to avoid overheating or overcooling, resulting in degradation of material properties.

5. Select the forging ratio in practical applications

Aero: Due to the very high performance, higher forging ratios are usually chosen (5:1 to 6:1).

The gas turbine disc part:forging ratio is usually 3:1 to 4:1 to ensure uniformity of the material and fatigue resistance.

General structural parts: For products with relatively low performance requirements, the forging ratio can be appropriately reduced to 2:1 to 3:1.

6. Optimization of forging process

Simulation analysis: The forging process parameters are optimized through finite element simulation and other methods, including forging ratio, deformation rate and temperature distribution.

Experimental verification: Through small-scale experimental production, the rationality of the forging ratio was verified and adjusted based on the experimental results.

Metal (Shanghai) Co., Ltd. was established in 2004 and specializes in the research, development, production, processing and sales of mid-to-high-end metal materials at home and abroad; its cover metal such as , steel, alloy steel, , etc. The has long-term and with many and well-known , and is good at the of and of metal such as and and high-end . Now, it has grown into a famous distributor in the high-end metal materials industry.

Summary, High temperature alloy> The choice of forging ratio requires comprehensive consideration of factors such as alloy type CNC parts, product use and process conditions, usually between 2:1 and 6:1. A reasonable forging ratio can effectively improve the tissue performance of the material and improve the quality and reliability of the product. Through scientific process design and optimization, high-temperature alloy forging can better meet the needs of high-performance fields.
