Structure, composition, and mechanical properties of thin films of transition metals diborides

Strategy for simultaneously increasing both hardness and toughness in ZrB2-rich Zr1−xTaxBy thin films

“…[13][14][15][16][17] Recently, TM diborides have been receiving increasing attention as the next generation of refractory, hard ceramic protective thin films for replacing TM nitrides in many applications. [18][19][20][21] TM diborides are already being employed as coatings on cutting tools [22][23][24][25] and engine components, [26][27][28] as well as for use as diffusion barriers in microelectronics. [29][30][31] While TM diborides are inherently hard, that alone is not sufficient to prevent failure in applications involving high stresses, since hardness is typically accompanied by brittleness leading to crack formation and propagation.…”

Facile and scalable synthesis of Ti5Si3 nanoparticles via solid-state route in an autoclave

“…In recent years, alloys systems have attracted widespread attention from researchers home and abroad, because of their excellent physical and chemical properties [1][2][3]. Metal silicides are a broad family of refractory intermetallic compounds between transition metals and silicon.…”

“…Metal silicides are a broad family of refractory intermetallic compounds between transition metals and silicon. Titanium silicide (Ti 5 Si 3 ) has attracted considerable attention due to its outstanding properties including high melting temperature (2122 °C), low density (4.32 g/cm 3 ) and high hardness, as well as excellent strength at elevated temperature and high oxidation resistance, which consequently promote Ti 5 Si 3 as a promising material for hightemperature structural applications [4][5][6][7].…”

Mechanical Property of Composite Material Based on Map-Reduce Model

“…And its basic method has the solid quantum theory and the quantum chemistry theory. The rise of first principle calculations based on quantum mechanical techniques takes a prominent place in computational material science with the help of supercomputers [4]. The movement towards creating a material database using simulation opens a new way of seeking and designing new materials [5][6][7][8].…”

“…The movement towards creating a material database using simulation opens a new way of seeking and designing new materials [5][6][7][8]. Such movement is also occurring in the field of catalysts where desired chemical reactions are evaluated using first principle calculations [9][10]. With the rapid increase of supercomputer development, creating material databases using first principle calculations is gaining popularity, yet accessing and manipulating the data for predicting new undiscovered materials has yet to be realized.…”
