Ni-26Al alloys （ atomic fraction

%） was prepared by laser-induced self-propagating reaction synthesis. Effects of milling time

such as 0

5 and 10 h

on the density、microstructure、composition and mechanical properties of the Ni-26Al prepared were investigated by density measurement

SEM （scanning electron microscope）

XRD （X-ray diffraction） and tensile testing. The results show that the sintered alloy is composed of Ni3Al and γ- Ni 、Al2O3 phases. The sintering performance of the alloy prepared is improved increasing with increasing in milling time

and after 10 h milling

the density

Rockwell hardness and wearing capacity are 5.85 g/mm3

62 HRC and 4.43×10-4 g/mm2

respectively.
