16. Formation of silicon nitride based materials by nitridation and sintering
Sammanfattning : Todays demands on silicon nitride based materials for structural applications focus on microstructures rendering high strengths and reliability at reasonable costs. This work was mainly aimed at production of sialons for these types of applications by nitridation with subsequent sintering. LÄS MER
17. Volume Change Effects during Solidification of Alloys
Sammanfattning : Volume change during solidification is an important concept in achieving of casting soundness. The solidification shrinkage can cause different defects in the ingot casting as well as the shape casting. The volume change due to phase transformation during solidification is the other concept which has to be studied. LÄS MER
