Paper Title:
Research on Direct Laser Sintering of Ni-Alloy Powder and Microstructure Feature
  Abstract

The direct laser metal sintering experiments were carried out with nickel alloy powder material system. The melting–solidification approach was discussed. Microstructure and components of DLMS-process sample were analyzed. The incomplete liquid phase sintering is the main mechanism of the melting-solidification approach. In powder material system, the additive copper improves the wettability of melting material, and minimizes the balling phenomenon. The equiaxial dendrite and the dendrite are the primary crystal morphologies. The compositions of materials are distributed uniformly.
