Mechanical performance indicators such as tensile strength and yield strength of titanium rods and their application in different fields

1. Mechanical performance indicators of titanium rods
Tensile strength
Tensile strength refers to the maximum force that a titanium rod can withstand during the stretching process, which reflects the material's ability to resist tensile damage. For titanium rods, their tensile strength is usually high, and the specific value varies depending on the alloy composition and heat treatment state. For example, the tensile strength of TC4 titanium rods is generally ≥895MPa, and some high-quality products can even reach 925MPa or more.

Yield strength
Yield strength refers to the stress that a titanium bar rod undergoes when it begins to undergo obvious plastic deformation during the stretching process. It indicates the critical point at which the material transitions from the elastic stage to the plastic stage, and is also a key parameter for measuring the bearing capacity of titanium rods. The yield strength of TC4 titanium rods is generally ≥825MPa, and high-quality products may be higher.

Elongation
Elongation refers to the increase in the length of a titanium rod relative to its original length after it breaks during stretching. It reflects the plastic deformation capacity of the material, that is, the degree of irreversible deformation that can occur in the material during the stress process. The elongation of TC4 titanium rod is usually ≥10%, and some products can reach more than 15%, which provides good conditions for its processing and forming.

Impact toughness
Impact toughness refers to the amount of energy that a titanium rod can absorb when subjected to an impact load. It measures the material's ability to resist impact damage and is of great significance for evaluating the performance of titanium rods under dynamic loads. The impact toughness of TC4 titanium rods is usually around 450-700KJ/m², showing good impact resistance.

Hardness
Hardness refers to the ability of a titanium rod to resist being engraved or scratched, which reflects the ability of the material's surface to resist local plastic deformation. The Rockwell hardness of TC4 titanium rods is generally between 31 and 35HRC, showing a high surface hardness.

2. The impact of mechanical performance indicators on applications in different fields
Aerospace field
In the aerospace field, titanium rods are widely used in the manufacture of structural parts such as frames, beams, trusses, etc. for aircraft, rockets, etc. due to their high strength, low density and good corrosion resistance. High tensile strength and yield strength ensure that titanium rods will not break or deform when subjected to huge loads, while good elongation and impact toughness improve their reliability in complex stress environments.

Medical field
In the medical field, titanium rods are widely used to manufacture medical devices and implants, such as artificial joints, dental implants, etc., due to their good biocompatibility, corrosion resistance and mechanical properties. High tensile strength and yield strength ensure that titanium rods can withstand long-term stress and loads in the human body, while good plasticity and toughness help reduce the stimulation and damage of implants to the human body.

Chemical field
In the chemical field, titanium rods are widely used to manufacture various chemical equipment and pipelines, such as reactors, storage tanks, heat exchangers, etc., due to their excellent corrosion resistance. High tensile strength and yield strength ensure that titanium rods will not deform or break when subjected to high pressure and high temperature, while good elongation and impact toughness improve their safety in emergencies.

Sports equipment field
In the field of sports equipment, titanium rods are used to manufacture golf clubs, fishing rods, bicycle frames, etc. due to their high strength, low density and good corrosion resistance. These equipments need to withstand high-intensity impact and vibration, so the materials are required to have extremely high strength and toughness. The mechanical properties of titanium rods just meet these requirements, making them widely used in the field of sports equipment.
