Mechanical deformation of WC–Co composite micropillars under uniaxial compression

In thiswork,WC–Co micropillars machined by focused ion beamhave been tested under uniaxial compression to investigate the stress–strain behavior and associated deformation mechanisms. The results indicate that yielding phenomena is evidenced by multiple strain bursts. Experimental data is found to f...
