The Ni P/M steel are mixtures of soft phase and hard phase, hence improving the mechanical properties by reducing the susceptibility of breach.

In order to produce dry sanding paper applied to soft materials, the slurry coating was prepared by smearing unblocked materials according to the phase change principle of endothermal agents.

The mechanical property and processing property of soft PVC/ABS alloy were tested, the fracture surface structure of the sample and compatibility of the two phases were characterized.
