Grain Refinement Strengthening

A new nanomicro composite self-lubricating ceramic tool material was prepared with vacuum hot pressing technique. The effect of nanoAl2O3 powders on the microstructure and mechanical properties of nanomicro composite self-lubricating ceramic tool material was investigated. With the increase of nanoAl2O3 content, the hardness and fracture toughness first up then down. When the nanoAl2O3 content is 4 vol.%, the flexural strength, hardness and fracture toughness reaches 562 MPa, 8.46 MPa·m1/2 and 18.95 GPa, respectively. The microstructure and mechanical property of nanomicro composite self-lubricating ceramic tool material can be improved by the grain refinement strengthening of nanoAl2O3.

Microstructure And Mechanical Property

Comparison of microstructures between LPSed and SSSed SiC ceramics were made. Several kinds of structure defects for LPSed SiC were emphasized to discuss. They related with whole flow path of processing, compositional design of powder mixture, spray granulation of powder mixture, milling, shaping, and sintering control. All could affect the microstructure and mechanical property of resultant ceramics.
