Influence of Microcrystalline Wax on Properties of MIM Multi-Component Wax Matrix Binder

Zhang Jian,Huang Baiyun,Li Yimin,Li Songlin(State Key Laboratory for Powder Metallurgy,Central South University,Changsha 410083,China)  
The properties of PW-EVA-HDPE binder with the addition of MW were studied. It shows that the addition of MW from 1% to 30% (mass fraction) causes an increase in the tensile strength and a decrease in shrinkage of the binder. After blending PW with MW, the crystallation behavior of wax matrix changes, that is resulting in fine grain for the binder and more isotropic microstructure for the feedstock. The powder loading capacity increases and the feedstock becomes more homogeneous. The reason of the modification is also discussed.
