METHOD FOR PRODUCING ALUMINUM-TITANIUM COMPOSITION MATERIAL Russian patent published in 2005 - IPC

Abstract RU 2255849 C1

FIELD: production of composition materials having special thermal properties by means of energy of explosion matters.

SUBSTANCE: method comprises steps of assembling pack of layers of aluminum and titanium; explosion welding of it and annealing. Relation of specific mass of explosion to specific mass of aluminum layer is in range 1.11 - 5.0. Explosion matter charge features detonation rate 2250 - 3300 m/s. Annealing is realized due to heating up to temperature exceeding that of aluminum melting by 1.06 - 1.14 times for 0.5 - 2 hours in order to form solid heat protection intermetallide layer. Then material is squeezed by means of steel punches by 20 -50% of thickness of aluminum layer subjected to simultaneous crystallization.

EFFECT: normalized heat exchange between layers of aluminum and titanium due to presence of intermetallide layer of optimal thickness in zone of joining of aluminum and titanium.
