Room and high temperature mechanical properties of Mg2Si, Mg2Sn and their solid solutions

Impact of the Dopant Species on the Thermomechanical Material Properties of Thermoelectric Mg2Si0.3Sn0.7

“…The mobility (µ) was estimated using the equation ς = neµ where ς is the electrical conductivity, n is the charge carrier density, and e is the charge of an electron. Electronic transport properties of the samples are shown in Table 3 Our previous work has proven that the material shows a linear dependence of elastic moduli on x [24]; this work also provides evidence on the little difference in the mechanical properties we would expect for such small differences in composition.…”

“…Its measuring principle is based on the free vibration of a sample (bar or pellet) set on top of supports. It has been extensively described by other authors, as well as in our previous work [24,36]. Young s modulus measurement was done using a device from Integrated Material Control Engineering NV (Genk, Belgium).…”

“…Contacting technology for Mg 2 Si-Mg 2 Sn has shown substantial progress as several candidate schemes have been evaluated [18][19][20][21][22] and their thermal stability assessed [23]. Mechanical properties have been studied, with our previous work detailing the temperature and composition dependent elastic behavior for the whole solid solution series [11,[24][25][26].…”

Applications of thermodynamic calculations to practical TEG design: Mg2(Si0.3Sn0.7)/Cu interconnections

“…As mentioned before, Mg 2 (Si 0.3 Sn 0.7 ) is a homogeneous pellet with no microscopic dephasing, 7 AE 3 mm grain size and a pellet density of $97% (aer the powder consolidation at 700 C). 42 $In the nal situation, aer 10 min of joining at 600 C in a direct sinter press, a reacted IZ can be observed with several new interfaces. A typical microstructure of the IZ is presented in Fig.…”

Станнид Mg-=SUB=-2-=/SUB=-Sn под давлением: результаты эволюционного поиска из первых принципов

“…Одним из наиболее интенсивно исследуемых в последние годы соединений магния, наряду с силицидом Mg 2 Si ( [1][2][3][4]) и германидом Mg 2 Ge, ( [5][6]) является станнид Mg 2 Sn ( [7][8][9][10][11]). В связи с относительно высокой температурой плавления T = 1030 K [12] и хорошей электропроводимостью станнид Mg 2 Sn подходит для использования в качестве термоэлементов в промышленном производстве [13,14].…”
