The mechanical properties of metal materials refer to the characteristics exhibited by these materials under the action of external forces. These include strength, hardness, elasticity, plasticity, impact toughness, fatigue strength, etc.
The ability of metal materials to resist failure under load is known as mechanical property (or mechanical strength). Common mechanical properties include: strength, plasticity, hardness, impact toughness, resistance to repeated impacts, and fatigue limit.
The mechanical properties of metal materials are the main basis for part design and material selection. Different properties of external loads (such as tension, compression, torsion, impact, cyclic loading, etc.) result in different mechanical properties required from metal materials. Common mechanical properties include: strength, plasticity, hardness, impact toughness, resistance to repeated impacts, and fatigue limit.
The commonly mentioned mechanical properties include: elasticity, plasticity, stiffness, age sensitivity, strength, hardness, impact toughness, fatigue strength, and fracture toughness. Elasticity: The property of metal materials to deform under the action of external forces, and to return to their original shape once those forces are removed. Plasticity: The ability of a metal material to undergo permanent deformation under external forces without suffering damage. Stiffness: The ability of a metal material to resist elastic deformation when subjected to forces. Strength: The ability of metal materials to resist deformation and fracture under external forces. Hardness: The ability of a metal material to resist being pressed into by a harder object. Impact toughness: The ability of a metal material to resist fracture under impact loads. Fatigue strength: The maximum stress to which a metal material can be subjected under numerous repeated or alternating loads without fracturing. Fracture toughness: A performance parameter that indicates a material’s ability to resist the unstable propagation of cracks. Mechanical properties are a set of common indicators for metal materials, and they are important material property parameters used in the design of mechanical products. In general-purpose mechanical products, mechanical parts are used at normal temperature and pressure in media that are not highly corrosive; therefore, the special requirements under special operating conditions are generally not taken into account. However, due to the wide variety of uses for mechanical products, the loads experienced by various mechanical components during use also differ, which results in slight variations in the mechanical property requirements of the specific materials chosen in product design.
