PRECIPITATION STRENGTHENING BEHAVIOR OF Al-Cu-Mn ALLOYS WITH THE EFFECT OF CASTING SEGREGATION
Al-Cu-Mn is one of typical heat-treatable cast alloys with high strength which has been widely used in aerospace and automobile industries. The complete manufacturing process for AlCu-Mn components includes low pressure die casting, T6 heat treatment and machining. It has been found that the property in former process has been transferred to the sequent step with considerable effect. In this pa...
متن کاملTEM INVESTIGATIONS OF WC-Co ALLOYS AFTER CREEP EXPERIMENTS
Carbide tungsten cobalt alloys were deformed in compression or in three point bending in a temperature range 1000-1350°C and in a stress domain 30-1000MPa. In these conditions, the stress exponent n of WC-CO alloys is a function of only the cobalt volurnic ratio and tends tow rds n = 1 for pure B carbide. The apparent activation energy is 550 kj mole. T.E.M. investigations on pure carbide defor...
متن کاملPrecipitation in stretched Al - Cu - Mg alloys with reduced alloying content studied by DSC , TEM and atom probe
The hardening and microstructural evolution during ageing of a Al-1.2Cu-0.5Mg and a Al-1.2Cu-1.2Mg (at.%) alloy has been investigated. Artificial ageing at 150°C of stretched and naturally aged samples initially (up to about 48 h) leads to very limited further strengthening, but ageing at 190°C results a quick increase in strength. Detailed microstructural investigation using differential scann...
