Microscopic mechanical properties of TiB2/A390 composites studied using in-situ synchrotron X-ray diffraction
Source abstract
Abstract
This study investigates the effects of TiB 2 ceramic particles on the mechanical and wear properties of 6 wt.% TiB 2 /A390 composites prepared via semi-solid state technology. Transmission electron microscopy (TEM) was employed to examine the interfacial structure of the composite, while in-situ synchrotron X-ray diffraction was used to study the micromechanical behavior during tensile testing.. The load transfer behavior between the Al matrix, primary Si and TiB 2 was analyzed by tracking the lattice strain, diffraction intensity and broadening of different diffraction peaks during the tensile process. The results show that the addition of TiB 2 significantly enhances the composite’s ultimate tensile strength and elongation by 61% and 62%, respectively. Furthermore, friction and wear tests revealed that TiB 2 improves the wear resistance of the composite, wear depth and wear area are minimized,reducing the friction coefficient and wear rate compared to the base A390 alloy.
