摘要：
High density sintering of austenitic steels such as 304L and 316L involves a combination of relatively high temperature (>1300 degrees C) and extended sintering time. This study shows an austenitic stainless steel can be sintered to near theoretical density at temperatures near 1240 degrees C using boron additions. Both the amount and the precompounded form of the boron play a role in determining the sintered microstructure and properties. A combination of high mechanical properties with good corrosion resistance is obtained in an austenitic steel containing as high as 0.8w/o boron. Besides densification, the sintering cycle must consider coarsening above the solidus temperature.
