چکیده انگلیسی
We attempted to produce a porous Ti-20 at% Al alloy by pressure-sintering of a mixed powder of Ti and Al with a NaCl space holder to achieve porosity of 60%. As-sintered specimens exhibited an inhomogeneous microstructure consisting of Ti particles surrounded by a Ti-Al alloy layer. However, a nearly single-phase Ti3Al microstructure appeared in the porous specimen heat-treated at 1300 °C, which shows high plateau-stress level of approximately 100 MPa resulting in high absorption energy. Thus, controlling the microstructure for the formation of the Ti3Al single-phase would be effective to achieve high energy absorption capacity of the porous Ti-Al alloy.
