Hosted by the Chinese Society for Metals（CSM）and China Power Metallurgy Alliance (CPMA), the 2018 World Congress on Powder Metallurgy (WORLDPM2018）opened in Beijing on September 17. It is the first time that the biennial event, which is the foremost one for the international powder metallurgy community, has been held in China since its first congress dating back to 58 years ago. There were approximately 1,200 experts and scholars from 32 countries participating in the Congress this year, among whom are Xu Guanhua, Gan Yong, Huang Boyun, Li Yuanyuan, Wang Huaming, Dong Yang, Bernd Kieback, Matthew Bulger, and so on. Academician Wang Huaming delivered an invited report titled Addictive Manufacturing for High-Performance, Large, Critical Metallic Components and its Impacts on Advanced Equipment Manufacturing Industries.
At the opening ceremony, the Organizing Committee of the Congress announced the winners of WORLDPM2018 PM Product Award, which is set up to reward the high-end equipment featuring great innovation, influence and technological breakthroughs and enjoying a promising prospect of application. The prize went to the product Large Complex and High Performance Components of High Strength and High Damage Tolerance Titanium by Laser Addictive Manufacturing jointly developed by the National Engineering Laboratory of Additive Manufacturing for Large Metallic Components of Beihang University and the AVIC the First Aircraft Institute, which ranked first among the ten rewarded products. The achievement demonstrates the research capabilities of Beihang University in this field.
The above mentioned awarded product proposes and realizes the design and manufacturing of a large complex hollowed-out lightweight titanium whole structure of the airplane. The optimization of one structural topology reduces the weight by 60% (over 260kg), and another simplifies a connecting structure of 6 forgings and 69 threaded bolts into a single integrated structure of high performance and high reliability. It has developed new methods of large complex and high performance components with high strength and high damage tolerance titanium by laser addictive manufacturing, which is vital to the improvement of equipment safety.
The team led by Academician Wang Huaming from the National Engineering Laboratory of Additive Manufacturing for Large Metallic Components of Beihang University has always been engaged in research on the additive manufacturing technology of key whole large high-performance metal components in collaboration with a number of key units in aeronautics and astronautics. Their hard work of over 20 years has sent China to the forefront of the world in the related fields.
