In order to shield the harm of neutron and gamma rays,Al/W/Gd2O3 composite is made by adding W into Al/Gd2O3 material.The performance of Al/W/Gd2O3 composite in shielding neutron and gamma rays is simulated and calculated by using Monte Carlo statistical test method and MCNP5 particle transmission software.Al/W/Gd2O3 composites are prepared by discharge plasma sintering(SPS),and their morphology and phase structure are analyzed by means of SEM and XRD.It is indicated that the tensile strength of Al/W/Gd2O3 composites is higher than that of Al matrix composites.The tensile fracture morphology shows that the fracture mode of the composites belongs to trans granular fracture.
