Compressive Property Comparisons Between Laser Engineered Net Shaping of In Situ TiBw-TMCs and Cp-Ti Materials
Titanium (Ti) and its alloys are widely used in chemical, astronautical, and biomedical
industries. However, their poor load endurance properties affect their fields of applications
especially under severe loading conditions. To enhance these properties, TiBw reinforcement
was synthesized by in situ chemical reaction between elemental Ti and boron. Strong interfacial
bonding between TiBw reinforcement and Ti matrix was obtained due to the in situ chemical
reaction. Owing to its capability of producing difficult-to-machine bulk composites with uniform
properties, laser engineered net shaping (LENS) technique was utilized to fabricate TiBw
reinforced Ti matrix bulk composites. Few researches have been reported on these three-dimensional metal based bulk composites by using LENS. In this work, effects of TiBw
reinforcement and laser power on compressive properties were investigated. The microstructures
of the fabricated parts were observed and analyzed by using scanning electron microscopy.Mechanical Engineerin
