Fig. 1: The ultrafast shaping and sintering (USS) process.
From: Programmable and rapid fabrication of complex-shape ceramics
a The green compact that exhibits high brittleness and poor processibility. b The working principle of the USS process that relies on the cooperation between the mechanical and thermal fields, where the blue and red arrows denote mechanical and thermal processes respectively. Specifically, two key points: (i) sufficient mechanical loads to guide the ceramic powder compacts; (ii) proper thermal field to activate the good deformability of the green compact. The porous-state ceramics comprises ceramic particles (yellow circles) and air gaps (blue area). c Photographs of the USS-fabricated arch-shape and twisted BT ceramics.
