The porous superalloy materials with hollow spherical pores were fabricated by using metal powder sinte- ring process.The scanning electron microscope (SEM) observation was applied to the test samples and it revealed that the pores of the porous material exhibited a uniform distribution and the apertures were of same size in principle. The sintering necks appeared between adjacent particles on metal skeleton after sintering.The mechanical properties of the test samples were analyzed and the result showed that this kind of materials possessed excellent energy absorp- tion capability,and the compression resistance decreased with increasing the porosity and aperture.
