What are the Disadvantages of High - Strength Materials?

 

In Terms of Processing Difficulty

 

Difficulties in Forming Processing
High - strength materials usually have high yield strength and hardness, which makes them face a lot of challenges during the forming process. For example, during forging, stamping, or rolling of metallic materials, high - strength materials require greater forming force. Take automobile body manufacturing as an example. Due to its high - strength characteristics, high - strength steel plates need higher pressure to be deformed during the stamping process, which requires higher - performance stamping equipment. Moreover, cracking is more likely to occur during the forming process because the material's deformability is relatively weak and it's difficult for it to adapt to the shape change of the mould as smoothly as low - strength materials.

 

Great Difficulty in Machining
In terms of machining, the high hardness of high - strength materials can lead to aggravated tool wear. For example, when turning or milling high - strength alloy steel, the cutting edge of the tool is prone to wear, thus reducing the machining accuracy and requiring frequent tool replacement, which increases the machining cost. At the same time, due to the high strength of the material, the cutting force generated during the cutting process is relatively large, which may cause the deformation and vibration of the workpiece and further affect the machining quality.

In Terms of Welding Performance

 

High Tendency to Welding Cracks
High - strength materials are prone to cracks during welding. This is because during the welding process of high - strength materials, the cooling rate of the heat - affected zone is relatively fast, and the welding stress generated is relatively large. When the welding stress exceeds the strength limit of the material, cracks will occur. For example, when welding high - strength aluminum alloy, due to the high thermal conductivity of the aluminum alloy, heat dissipates quickly during the welding process, and the microstructure of the heat - affected zone changes significantly, so it's easy to form hot cracks.

 

Decline in Welding Joint Performance
The welded joint area is often the weakest link in the structure of high - strength materials. The welding process may change the microstructure of the material, leading to a decline in the strength, toughness and other properties of the joint. For example, when welding high - strength steel, the hardness of the welding joint may change, with local hardening or softening phenomena, which reduces the bearing capacity and fatigue resistance of the joint and affects the safety and reliability of the entire structure.
