After nearly 30 years of continuous research and development, the company team has carried out titanium alloys (TA15, TB6, TC4, TC11, TC18, TC21, Ti60, Ti60A, titanium alloy, etc.) in major equipment manufacturing fields such as aviation, aerospace, navigation, energy, power, and petrochemicals. Ti81, ...), high-strength steel (A-100, AF1410, 300M, 1Cr17Ni2, 15-5PH, 316L, ...), heat-resistant alloy/high temperature alloy (Rene95, Rene88, DZ408, GH4169, ...), high-strength aluminum/aluminium lithium Research on the additive manufacturing technology of more than 100 high-performance and difficult-to-machine metal large and complex key components such as alloys, lightweight magnesium alloys, refractory alloys (Nb-W alloys, ...), has accumulated hundreds of thousands of third-party authoritative agency tests According to the engineering data, various grades of materials have established their benchmark values for laser additive manufacturing materials in accordance with the international metal material performance development and standardized MMPDS (Metalic Materials Properties Development and Standardization) specifications.

The company's laser additive manufacturing of titanium alloys and high-strength steel materials exhibits excellent comprehensive mechanical properties comparable to forgings, and has flexible and rich performance control methods and windows. According to customer needs, the performance of laser additive manufacturing products can be strengthened and plasticized. Performance indicators such as toughness, life, damage tolerance, etc. are 'adjusted on demand' to a certain degree. For example, our company's laser additive manufacturing of TA15 titanium alloy has common annealed mechanical properties comparable to forgings, and its fatigue ultimate strength is relatively excellent (increased by 30%-50%). The special heat treatment process invented by our company can maintain the material properties. On the basis of good strength, plasticity and fatigue and other key indicators, the fracture toughness is greatly increased by 50%, and the fatigue crack growth rate is reduced by an order of magnitude (service safety is significantly improved). As another example, the company's laser additive manufacturing of LMD-T1 titanium alloy, using comprehensive adjustment from alloy composition-laser additive manufacturing process-heat treatment process, can obtain the TC4 ELI titanium alloy with the best internationally recognized damage tolerance performance Equivalent fracture toughness and fatigue crack growth performance, but the strength is increased by nearly 30% compared with TC4 ELI. 

Laser additive manufacturing of directional fine columnar superalloys: primary dendrite spacing is 7.6 μm, secondary dendrites are 2.8 μm, there is no γ/γ‛ eutectic between dendrites, and no micro looseness; its initial melting temperature is more than traditional casting alloys Increase 8℃
