PROCESS OF DETERMINATION OF DEGREE OF DECOMPOSITION OF SOLID SOLUTION IN ALUMINIUM ALLOYS AFTER THERMAL TREATMENT Russian patent published in 1997 - IPC

FIELD: metallurgy, investigation of action of thermal treatment on structure and physico-mechanical properties of aluminium alloys. SUBSTANCE: proposed process of determination of degree of decomposition of solid solution in aluminium alloys after thermal treatment includes determination of specific conductance of tested material and additional determination of conductance of same material after rehardening and full annealing. Degree of decomposition of solid solution is found from relation , where 6 is degree of decomposition of solid solution; γ is specific conductance of material after thermal treatment under tested state; g_o is specific conductance of material after rehardening; γ_м is specific conductance of material after its annealing under annealed state. EFFECT: enhanced authenticity of process. 5 dwg
