| Heat treating process creating metallurgical bonding of
particles | |
| Carried out in liquid or combined solid-liquid phase | |
| Shrinkage can occur if liquid phase present | |
| Provides a substantial increase in strength of the workpiece | |
| Can be above or below melting temperature of the particle (0.1 - 0.3% shrinkage if below; 40 - 60% if above) |
