Are ceramics stretchable? For the first time, Chinese scientists achieved →_Plasticity_Team_Chen Ke

The reporter learned from the University of Science and Technology Beijing that the team of researcher Chen Kexin of the school, together with the team of Professor Wang Jinshu of Beijing University of Technology and Professor Huang Mingxin of the University of Hong Kong, have achieved room temperature large deformation tensile plasticity of ceramics for the first time in the world. This latest research result was published in "Science" on July 26.

On the basis of realizing the compression plasticity of ceramics, Chen Kexin's research team and his collaborators pioneered the strategy of "borrowing dislocations" from metals, further achieving large deformation tensile plasticity of ceramics. The tensile deformation of ceramics can reach 39.9%, and the strength is about 2.3GPa, which subverts people's consistent understanding that "ceramics cannot have tensile plasticity".
