PROCESS FOR PRODUCING POROUS SINTERED ALUMINUM, AND POROUS SINTERED ALUMINUM

摘要

This method for producing porous sintered aluminum includes: mixing aluminum powder with a sintering aid powder containing a sintering aid element to obtain a raw aluminum mixed powder; forming the raw aluminum mixed powder into a formed object prior to sintering having pores; and heating the formed object prior to sintering in a non-oxidizing atmosphere to produce porous sintered aluminum, wherein the sintering aid element is titanium, and when a temperature at which the raw aluminum mixed powder starts to melt is expressed as Tm (°C), then a temperature T (°C) of the heating fulfills Tm-10 (°C) ‰¤ T ‰¤ 685 (°C).
