Incorporating Mg into the Si sub-lattice of molybdenum disilicide

Electric Current Activation of Sintering: A Review of the Pulsed Electric Current Sintering Process

“…The combination of prior mechanical activation (high energy milling) on powders with a subsequent sintering or reactive sintering by the PECS process has been utilized to simultaneously synthesize and densify nanostructured, intermetallic, and composite materials 45–47 . For example, using this approach, it was shown that MoSi 2 could be microalloyed successfully with Mg, 48 a long sought after goal, facilitating a reduction in the ductile‐brittle transition temperature in accordance with theoretical predictions 49 . Accomplishments were also made in the formation of functionally graded materials (FGMs) 50–52 and in the joining (bonding) of materials 53–55 …”

Investigation of MoSi2 formation in the presence of copper by self-propagating high-temperature synthesis

“…The evaluation of combustion front was carried out using the time-resolved X-ray diffraction (TRXRD) technique and results showed the direct formation of MoSi 2 in classic mode of SHS. Also it was observed that for modifying the properties of MoSi 2 , sometimes a third element such as Al or Mg might be added to the binary mixture [16,17].…”

Synthesis and characterization of Nb5Si3/Nb functionally graded composites

“…These include the addition of second phase particles and microalloying, as has been investigated extensively in the case of MoSi 2 [5,10]. Ductile-phase toughening also has been used to significantly improve the toughness of Nb 5 Si 3 , usually by inclusion of Nb particles [7,8].…”
