Abstract
The A15 phase Mo3Si is an important constituent of a new class of silicides based on Mo-Si-B. In this research it will be shown that, contrary to publ ished results, single-phase Mo3Si is slightly off-stoichiometric. In additi on, it remains single phase in a small composition range. Its room temperat ure fracture toughness is on the order of 3 MPa m(1/2). The compressive str ength at 1400 degrees C in argon decreases with decreasing strain rate and increasing Si concentration.
