RISAn investigation on the mechanism and reaction sequence of scheelite-magnesium mixtures during mechanical milling
The mechanism of mechanically-induced self-propagating reaction (MSR) of scheelite with magnesium during reactive ball milling was investigated using in-situ monitoring of the vial temperature, X-ray diffraction analysis ...
A discussion on the formation mechanism of tungsten carbides during mechanical milling of CaWO4MgC mixtures
Abstract
Synthesis mechanism of tungsten carbides via mechanically-induced self-propagating reaction (MSR) was investigated. Scheelite (CaWO4) is the main ore of tungsten and was used as precursor of tungsten ...
Fabrication of Fe/Al2O3 composite foam via combination of combustion synthesis and spark plasma sintering techniques
Abstract: Iron-alumina composite foam was prepared through combination of self-propagating hightemperature
synthesis (SHS) and spark plasma sintering (SPS) in less than 80 seconds, starting from
Al, Fe2O3 and ...
بررسی امکان تولید فوم فلزی از پودر آهن به روش SPS
چکیده
فرایند SPS یکی از روش های نوین در تف جوشی قطعات متالورژی پودر می باشد. در این روش در مدت زمانی کوتاه با تخلیه پالس های الکتریکی به توده پودر، امکان تف جوشی و چگالش قطعات با ایجاد گرمای ژول وجود دارد. در این ...
Feasibility study of porous Fe-Al2O3 composite fabrication through combination of SPS and SHS processes
Abstract
In this study, fabrication of Fe-Al2O3 porous composite through combination of two non conventional
material processing techniques of spark plasma sintering (SPS) and self propagating high-temperat ...
Fabrication of Aluminum–Graphite Composites by SPS Method
Abstract - The current study is focused on the synthesis of Aluminum-Graphite composites (Al-C) by Spark Plasma
Sintering (SPS) method. In order to investigate the synthesis process, the different main parameters ...
