A Detailed Guide to Titanium Forging

 

Are you interested in purchasing titanium forged products? Nowadays, individuals can easily find a reputable company that manufactures such forgings and ships them to customers. These professionals make products from raw titanium, subjecting it to all of the necessary stages until it meets the forging needs of clients.

The metallurgical properties of this metal are of essential importance in the production of alloys. The process of forging titanium results in the production of cylinders, rolled rings, bars, disks, and other forgings.

The guide below will introduce you to the properties, alloys, and forging of this metal.

Properties

Titanium is one of the most prominent metallic elements, popular for its remarkable strength, higher than that of aluminum and low-carbon steel. Nevertheless, the strength has no negative effect on its weight, as this material is much lighter than stainless steel.

Moreover, titanium is boasted for its resistance to corrosion, which is almost as high as the corrosion resistance of platinum. The element shows excellent resistance to seawater, chlorine gases, acids, and saltwater. When exposed to high air temperatures, its surface is covered with an oxide coating, impeding the process of corrosion.

Additionally, this metal is well known for its flexibility, low thermal expansion coefficient, and minimal requirements in terms of maintenance. Most importantly, titanium is touted to cause no harm to humans, being neither harmful nor toxic to the body. Also, people don’t experience an intense feeling of coldness when coming in touch with its surface.

Types of alloys

When combined with other metals, titanium leads to the creation of three sorts of alloys, those being alpha, alpha-beta, and beta alloys. These are mainly created for their resistance to erosion and fire, along with their ability for a quick transfer of heat. Read here about the properties, heat treatment, and application of titanium alloys.

For instance, alpha alloys are thought to be the best when it comes to corrosion resistance. Their weldability and ductility make them popular in the engineering industry. Additionally, the variety of mechanical properties enables their use in the aerospace industry.

Furthermore, the strength levels of alpha-beta alloys are higher than those of alpha alloys, but their creep resistance to high temperatures is lower. In contrast, betta alloys lack the superior weldability of alpha alloys, but their strength is significantly higher. The presence of alpha stabilizers is known to enhance both their creep and corrosion resistance.

Forging

In the course of the forging process, when exposed to high temperatures, titanium, and its alloys are susceptible to contamination. It’s likely for oxygen, carbon, hydrogen, or nitrogen to contaminate the material unless the slugs are coated in liquid glass prior to the process.

Once the coating gets dry, it creates a protective layer that prevents all forms of contamination. Despite the protective coating, it’s still possible for the metal to get contaminated. In such scenarios, the contaminated thin layer on the surface can be removed with a grinding machine.

Moreover, the Beta phase is when titanium melts to a point ideal for forging and welding at 3038 ˚F. In contrast, the temperature during the Alpha phase doesn’t exceed 1625˚F. The Beta phase is considered optimal for forging, as the metal is still strong and resistant to corrosion. In order to avoid a reduction in ductility, the ultimate forging stage is performed at a temperature a bit lower than the one during the Beta phase.

In terms of deformation, alpha and beta alloys can be forged into various products at temperatures above 1400˚F. Nevertheless, forging these materials below 1400˚F is likely to result in products with lower quality due to the risk of cracking. The temperature during forging is of tremendous importance in order for the process to be successful. Therefore, any losses of heat are detrimental to the products’ quality, resulting in defects.

Finally, when titanium forgings need to be straightened, straightening cannot be done when the products are cold. This operation is best performed at a minimum of 716 ˚F to 980˚F.

Final word

This metal is light but strong, not losing its strength even at high temperatures!
