Abstract
Bubble dispersion strengthened copper (BDS-Cu) was synthesized by using the pyrolysis gaseous products of Poly (methyl methacrylate) (PMMA) during spark plasma sintering (SPS) process. Bubbles with an average diameter of 14 nm are densely dispersed in copper matrix with a dispersion distance 119 nm. Vickers׳ hardness of BDS-Cu is 400 MPa higher than that of pure copper. The strengthening effect is due to the dislocation pinning effect of bubbles.
