The variation of through thickness properties and structure of AA7010 thick plate
1997 (English)In: THERMEC 97: International Conference on Thermomechanical Processing of Steels and Other Materials, Warrendale, Pa.: TMS, cop. , 1997, p. 941-949Conference paper, Published paper (Other academic)
Abstract [en]

The variation of through thickness structure and yield strength of AA7010-T7451 100 and 150 mm thick plate was investigated. Grain sizes at different depths were determined by using optical microscopy and EBSP maps. Texture measurements were carried out, using x-ray technique and EBSP, at the same depths as grain size studies and tensile property tests were performed. EBSP technique was used to compare degree of recovered and recrystallized grain structure at different depths. Tensile testing and hardness measurements reveal through thickness variations in yield strength and hardness. Variations in composition through the thickness are also possible. The influence of texture on yield strength was discussed.
