Tsinghua University's Qbeam S350 and S600 received the first major technical equipment product certification.​


It is reported that the electron beam selective melting (EBSM®) equipment Qbeam S350 and Qbeam S600 independently developed by Tsinghua Zhishu have been successfully included in the "Beijing 2024 Third Batch of First (Set) Major Technical Equipment Catalogue", marking that the company's technical strength and innovation capabilities in the field of electron beam additive manufacturing have been authoritatively recognized again.

he Qbeam S350 uses the independently developed EG3.1 version electron gun and a single-crystal cathode, resulting in excellent beam spot quality and a long cathode life (≥800h). Combined with the independently developed electron beam calibration technology, the minimum beam spot diameter is as low as 180μm, enabling efficient and high-precision forming of 350×350×500mm³ dimensions. It supports the printing of a variety of high-performance metal materials, including titanium alloys and high-strength titanium alloys.

he Qbeam S600 leverages revolutionary multi-electron gun splicing control technology to successfully integrate four 6kW high-energy electron guns, overcoming the challenges of multi-gun/beam interference and complex splicing techniques. This enables a 600×600×700mm³ build volume, meeting the urgent need for efficient printing of large-scale parts. This innovation significantly improves production efficiency and cost-effectiveness while ensuring superior performance and broad applicability of the finished product.

随着我国第三代高性能碳化硅SiC纤维研发的突破性进展,SiCf/SiC复合材料在先进航空发动机热端部件的创新应用已切实可行。新一代高推重比航空发动机涡轮前温度约2400K(局部可达2700K),采用典型单循环冷却结构可实现冷效0.4~0.6;据此推算,新一代高推比航空发动机的典型服役工作环境中,高压涡轮部件面向燃气的壁面温度将高于1500℃,且承受高载荷和循环燃气冲蚀。使用三代碳化硅纤维的SiCf/SiC复合材料的可靠服役温度约为1350~1400℃。综合分析,面向新一代航空发动机SiCf/SiC复合材料高压涡轮部件应用,需要在其表面涂覆热/环境障(thermal/environmental barrier coating,T/EBC)多功能涂层,在满足环境障涂层的燃气环境腐蚀介质防护功能外,兼具热障涂层的热防护能力,保障SiCf/SiC复合材料部件的服役可靠性。

yeah, people need to really look at rare earth as advanced material science. And the key is getting ultra high purity RE alloys for these higher end applications.

RE has countless applications in extreme performance materials, and magnet is just the best known one.
Here is another example. RE-doped bearing steel with the worlds highest fatigue strength among all steels achieved by CAS IMR.

Nice, if you find more examples of this, please post them.

I think all the r&d into this stuff is going to yield some interesting results.
