Factors affecting tensile strength:

The tensile strength of pure nickel wire is affected by many factors, including but not limited to the following aspects:

• Temperature: As mentioned earlier, temperature has a significant impact on the tensile strength of pure nickel wire. Generally speaking, as the temperature increases, the tensile strength of pure nickel wire will decrease, and as the temperature decreases, the tensile strength will increase.
• Grain size: The grain size of pure nickel wire also affects its tensile strength. Smaller grain size usually means a material has higher strength, because small grain size can hinder the movement of dislocations. On the contrary, larger grain size may lead to easy slippage of dislocations, thus reducing the tensile strength.
• Alloying elements: The tensile strength of pure nickel wire can be changed by adding other elements through alloying. For example, adding a certain amount of chromium, molybdenum, iron and other elements can improve the tensile strength and hardness of pure nickel wire.
• Cold working deformation: Cold working deformation can improve the tensile strength of pure nickel wire by increasing its dislocation density. Cold working introduces more dislocations, increasing the material's strength. However, excessive cold working may lead to increased brittleness and thus reduced tensile strength.
• Grain boundaries and impurities: The grain boundaries and impurities of pure nickel wire will also affect its tensile strength. The interaction of grain boundary structure and dislocations may lead to localized stress concentrations, thereby reducing tensile strength. In addition, the presence of impurity elements may affect the lattice structure and interactions of pure nickel wire, thereby affecting its tensile strength.
• Processing technology: The processing technology of pure nickel wire, such as annealing, cold drawing, heat treatment, etc., will also affect its tensile strength. Appropriate processing techniques can improve the lattice structure and dislocation density, thereby increasing tensile strength.
