Different amounts of ZrB2 particles are added to a matrix constituted by AlN+SiC for the production of novel electro-conductive composites by hot pressing. The presence of ZrB2 particles makes the composites electro-conductive and improves many relevant mechanical properties, such as toughness, hardness and strength. The new materials can reach a fracture toughness of 4 MPa.m1/2 and strength of 504 MPa at 1400°C.

Abstract
Different amounts of ZrB2 particles are added to a matrix constituted by AlN+SiC for the production of novel electro-conductive composites by hot pressing. The presence of ZrB2 particles makes the composites electro-conductive and improves many relevant mechanical properties, such as toughness, hardness and strength. The new materials can reach a fracture toughness of 4 MPa.m1/2 and strength of 504 MPa at 1400°C.File in questo prodotto:
