Sintered materials offer both process and product performance opportunities
in a wide variety of fields. Some emerging opportunities
Debindo
defect-predicting software
Blister and
cracks are common defects in binder assisted forming. Defects can often
be directly linked to the method and rate of binder removal from a compact.
As a method of eliminating defects in manufacturing, a predictive tool
to determine when and if a defect will be produced has been developed.

Use
of Recycled Compaction Grade 316L
in Powder Injection Molding
This study involves
the use of 316L compaction grade scrap for use as a powder injection molding
powder. The reground and sieved powder was blended in various amounts
with gas atomized 316L powders and tested for sintering response. Regrind
contents of 10-20% result in only small decreases in sintered density,
but beyond 30% addition the sintering response was considered unacceptable.
With the use of boron as a sintering aid, large amounts of reground powder
may be used without penalty in sintered density; however, ductility is
reduced to 15% elongation. The estimated cost of the remilled and sieved
powder is $0.95/lb. Read
