To address this, surface modification through nitriding is common but can reduce fatigue strength due to grain-coarsening.
The research aims to enhance the tribological properties of titanium alloy by developing a low-temperature nitriding process. The previous study successfully applied this to commercially pure titanium, maintaining fine grains. This study specifically looks at low-temperature nitriding of Ti-6Al-4V alloy, characterizing the surface layer formed, and assessing its impact on the alloy’s 4-point bending fatigue properties.
Titanium Mechanical Properties
Unalloyed, commercially pure titanium has a tensile strength ranging between 275 and 590 MPa. This strength is mainly influenced by the oxygen and iron content; higher levels of these elements result in increased strength. For commercially alloyed titanium grades, the tensile strength varies from as low as 600 MPa (e.g., Ti-3A1-2.5V) to as high as 1250 MPa (e.g., Ti-15Mo-5Zr-3AI).
Pure titanium remains stable up to around 300°C, owing to its specific strength and creep resistance. More complex titanium alloys maintain high strength even at temperatures up to approximately 500°C.
The fatigue strength (after 10^7 cycles) is approximately half of the tensile strength, and welding does not significantly decrease fatigue strength. In seawater, both commercially pure titanium and titanium alloys show almost no decline in fatigue strength.
The fracture toughness of titanium alloys ranges from 28 to 108 MPa m^1/2 and is inversely correlated with tensile yield strength. The specific fracture toughness depends on microstructure, with alloys having acicular structures exhibiting higher fracture toughness.

High Carbon Steel
High carbon steel consists of a higher percentage of carbon (between 0.60% and 1.0%). It is known for its hardness and is often used for cutting tools, blades, and high-strength wires.
Types Of Carbon Steel & Its Uses
Low Carbon Steel Uses
Low carbon steel is the most common type of steel, accounting for about 90% of all steel produced. It is also the least expensive type of steel. Low carbon steel is made from iron ore and coal, and it contains less than 0.3% carbon. This makes it relatively soft and easy to machine. Low carbon steel is also ductile, which means that it can be easily formed into shapes without breaking.
Applications of Low Carbon Steel
Flat-rolled sheets and strips: Low carbon steel is the primary material used for the production of flat-rolled sheets and strips. These products are used in a wide variety of applications, including shipbuilding, wire manufacturing, vehicle bodies, and domestic appliances.
Wrought iron: Wrought iron is a form of low carbon steel with a minimal carbon content. It is valued for its hardness without brittleness, making it a good choice for applications such as fencing, gates, and railing.
Medium Carbon Steel Uses
Medium carbon steel is also known as mild steel. It is made from iron ore and coal, and it contains between 0.3% and 0.6% carbon. This makes it harder and stronger than low carbon steel, but it is still relatively easy to machine. Medium carbon steel is also ductile, which means that it can be easily formed into shapes without breaking. Medium carbon steel is widely used in construction, such as in buildings and bridges. It is also used in the manufacturing of cars, fridges, and washing machines.
Applications of Medium Carbon Steel
Structures: Medium carbon steel is widely used in the construction of buildings and bridges.
Axles, gears, shafts, and rails: Medium carbon steel is used in the manufacture of a wide range of machinery parts, such as axles, gears, shafts, and rails.
Pipelines and couplings: Medium carbon steel is used in the construction of pipelines and couplings.
Vehicles, refrigerators, and washing machines: Medium carbon steel is used in the manufacture of cars, refrigerators, and washing machines.
High Carbon Steel Uses
High carbon steel is made from iron ore and coal, and it contains between 0.6% and 1.0% carbon. This makes it very hard and strong, but it is also brittle. High carbon steel is not easy to machine, and it is not ductile. High carbon steel is used in the manufacturing of cutting tools, blades, punches, dies, springs, and high-strength wire.
Applications of High Carbon Steel
Cutting tools and blades: High carbon steel is the material of choice for crafting cutting tools and blades, such as knives, saws, and axes.
Punches and dies: High carbon steel is used in the manufacture of punches and dies.
Springs: High carbon steel is used in the manufacture of springs.
High-strength wire: High carbon steel is used in the manufacture of high-strength wire.

Conclusion
Carbon steel is widely used in the construction of buildings, bridges, pipelines, automotive components, machinery, and various tools. Its popularity stems from its strength, durability, and relatively low cost compared to other materials. However, it is important to note that carbon steel is susceptible to corrosion, so proper coatings or treatments are often applied to enhance its resistance to rust.
