Effect of high temperature heat-treatments on the strength of molybdenum disilicide

The influence of high-temperature heat-treatments in air at 1400 and 1550 deg C for 100 h on the bending strength of molybdenum disilicide (MoSi sub 2 ) at room temperature has been investigated. A heat-treatment at 1400 deg C has no influence on the strength but a heat-treatment at 1550 deg C signi...

Beschreibung
Zusammenfassung:	The influence of high-temperature heat-treatments in air at 1400 and 1550 deg C for 100 h on the bending strength of molybdenum disilicide (MoSi sub 2 ) at room temperature has been investigated. A heat-treatment at 1400 deg C has no influence on the strength but a heat-treatment at 1550 deg C significantly decreases the strength due to the formation of large pores in the bulk of the material.
