Cyclic deformation behavior of Mg–SiC nanocomposites on the macroscale and nanoscale

Metal-ceramic nanocomposites are promising candidates for applications necessitating light weight and excellent fatigue resistance. We produced Mg–SiC from mechanically milled powders, yielding a homogeneous nanocrystalline structure quasistatic strength values. Little is known, however, about the behavior of such composites. Here, we used load increase tests on macroscale to yield estimation values endurance limit. Fatigue increased significantly materials processed by powder metallurgical route. further investigated cyclic deformation under stress-controlled conditions nanoscale. Cyclic nanoindentation showed that indentation depth plastic decreased with increasing reinforcement content, hinting higher corroborating results macroscopic tests. Our therefore show reliably determines Mg offering possibility fast material analysis.
