Self-propagating high-temperature synthesis of silicides and nickel-titanium compounds

Combustion synthesis of TiNi intermetallic compounds

“…analysis of the nickel powder. This combustion temperature determination is approximately 250K higher than that determined by Itin et al [10][11][12][13] who used the combustion mode. The pressed pellets were formed in a cylindrical, tool steel die using two plungers.…”

“…This is compared with the combustion mode in which the pellet is ignited at one end. From this reasoning, it may be argued that the combustion temperature determined by Itin et al [10][11][12][13], which was 260K lower than the present work, was the result of a nonadiabatic combustion process. If this heat flow is too large, the combustion may be quenched.…”

“…diameter and density of the pellets) [10][11][12][13], than the thermal explosion mode. This is compared with the combustion mode in which the pellet is ignited at one end.…”

“…Recently, near equiatomic TiNi has received some attention because of its unique shape-memory properties. Recently, Russian researchers have used the combustion mode to synthesize the TiNi shape-memory alloy (SMA) [10][11][12][13]. 2 is the phase diagram of the Ti-Ni alloy system which indicates a melting point for the TiNi alloy of 1513 K. Conventionally, the alloy is produced by a vacuuminduction melting method [8,9].…”
