Based on the composition-microstructure multilevel design and the fabrication technology of large-scale components, several kinds of boron nitride ceramic matrix composites have been developed with in-situ reinforced phases such as silicon oxide, rare earth silicate and rare earth aluminosilicate glass.
In magnetic confinement nuclear fusion, a strong magnetic field is used as "magnetic container" to confine high-temperature plasma which is then heated to hundreds of millions of degrees to maintain continuous thermonuclear reactions. Because the fusion reactors are made of a wide variety of materials, the need to join dissimilar materials is apparently prevalent. Furthermore, all the joints are always subject to higher heat loads and serious plasma sputtering erosion. Accordingly, the joint reliability is of intense importance. However, joining of dissimilar materials with huge differences in composition, physical and chemical properties has always been the biggest bottleneck restricting their engineering applications.
The IV generation nuclear energy system is an important direction of advanced nuclear energy development. Focusing on the construction requirements of the "CFR600 sodium-cooled demonstration fast reactor", the special stainless steel welding material ER316H (KD) has been developed for the fourth-generation sodium-cooled fast reactor.
Bearing is the core part of mechanical equipment, and its primary failure form comes from contact fatigue failure. Because the fatigue failure of bearing mainly originates from non-metallic inclusions
On March 12, 2019, the austenitic stainless steel supporting ring with the world's largest diameter (15.6 meters) and the largest weight (150 tons) was successfully rolled in Jinan using the Additive Forging technology proposed by SYNL. This huge rolled ring is manufactured without welding
A continuous synthesis, deposition, and transfer technique for the fabrication of high-quality SWCNT thin films of meter-scale dimension with excellent optoelectrical performance is developed. SWCNTs are continuously synthesized by a floating catalyst chemical vapor deposition technique
