Determimning The Fracture Toughness of B4c-Nanotib2 Composite by using VIF Method at Different Loads
In this paper, Boron Carbide (B4C) nanocomposite samples with a volume of 8% of TiB2 were prepared and the
values of density, hardness and elasticity modulus were determined and then the fracture toughness (KIC) values were
calculated by using various KIC formulas with Vickers Indentation Fracture (VIF) test method using loads of 100 and 150 N
and their results were compared to each other. The results show that the new equation utilizing cracks leads to high accuracy
and efficiency compared to other relations.
