Launched a new nickel-based superalloy, MT-IN939

Inconel 939 (IN939) is a nickel-based superalloy primarily composed of nickel, chromium, molybdenum, and aluminum. The material exhibits an excellent balance of high-temperature strength, corrosion resistance, oxidation resistance, fatigue performance, creep strength, and hot and cold workability. It is ideally suited for manufacturing components for gas turbine engines operating in high-temperature environments above 850℃ and is widely used in aerospace, energy, and chemical industries.

In 2020, Tianjin's 3D printing output value will reach 1.5 billion yuan.

3D printing, also known as additive manufacturing, has become a core technology in the new industrial revolution in recent years. Its unique advantages enable close integration with new networks, advanced materials, and digital manufacturing. Our city's 3D printing related technologies started at the end of the last century. After years of development, we have established a certain foundation in 3D printing materials, equipment, and processes. Annual service revenue from 3D printing exceeds 100 million yuan, serving over 200 domestic users. However, overall, the 3D printing industry in our city is still in its infancy, occupying a small share of the national market and lagging significantly behind advanced countries and regions.

Domestically, the technology of metal direct sintering 3D printing has been successfully trial-produced.

It is introduced that Direct Metal Laser Sintering (DMLS) technology is the crown jewel in the field of 3D printing technology. Because this technology directly uses laser melting metal powder deposition, the density of the structural component can reach more than 99%, close to the material embryo of forging. Currently, internationally, this technology is mainly used to manufacture high-stress components and complex components, irregular components that cannot be processed by traditional processes. It can reach 90% to 95% of the strength of the same grade of metal, and has the characteristics of high precision and few forming limitations. It is widely used in the manufacturing of high-end precision parts and other fields.

New breakthrough in room-temperature 3D printing of metal objects

The development of this metallic gel began with a solution of micrometer-sized copper particles suspended in water. Scientists first added a small amount of gallium-indium alloy (EGaIn) and hydrochloric acid to the solution. The hydrochloric acid adjusted the pH of the water to 1.0, removing oxides from the EGaIn and temporarily turning it into a liquid metal. Then, the copper particle solution and the liquid EGaIn mixture were stirred, allowing EGaIn particles to adhere to the stronger copper particles, forming a metallic gel "network" of copper particles connected by EGaIn bridges in the aqueous solution. Methylcellulose was added to expand the mixture.

3D-printed bones successfully applied, freeing patient from metal 'armor'

Over the years, the advancement of orthopedic medical technology has been inseparable from the role of internal fixation devices. In the past, patients with fractures often had to lie in bed for a long time, relying on plaster casts or traction to stabilize the local bones and allow them to heal slowly. After the 1980s, internal fixation metal devices gradually entered clinical use, helping patients reconstruct bone structures and significantly shortening the recovery period. However, limited by traditional technology, only some regular-shaped internal fixation metal devices, either round or square, could be produced. Taking the atlas and axis, the most complex structures in the human spine, as an example, their shapes are irregular, and traditional implants are clearly unable to adapt to the complex structure of human bones.

Mastering core technologies in 3D printing metal powder to promote industry development. As a strategic emerging materials industry in the country, the lack of product standards has always plagued the development of the 3D metal printing industry.

The lack of product standards in 3D metal printing, a strategic emerging materials industry for the country, has long plagued the industry's development and hindered the connection of the industrial chain, including powder products, printing equipment, and product stability. In 2019, the company, in collaboration with domestic technological forces, overcame the technical difficulty of the non-flowability of Chinese aluminum alloy powder. In the same year, it broke through the Western technological barriers of 3 high-temperature alloy powders, allowing domestic aerospace and military industries to completely break away from their long-term dependence on foreign powders and solve the "bottleneck" problem of key powders.
