02 Too Hot to Handle: The Thermal Thresholds Where Sintering Stops Helping and Starts Hurting
Conventional wisdom in sintering holds that more heat accelerates densification and strengthens the final part — but the physics tell a more complicated story. Excessive firing temperatures routinely introduce grain coarsening, residual stress, and microstructural defects that erode mechanical performance in ways that standard inspection protocols often miss. Understanding where the thermal sweet spot lies, and why so many operations consistently overshoot it, is one of the more consequential ch
