Constitutive Model for Aluminum Alloys Exposed to Fire Conditions
|
An existing constitutive model for creep, developed by Dorn and Harmathy, is modified in order to be used for fire-exposed aluminum alloys. Two alloys, 5083-O/H111 and 6060-T66, are selected for the development of this constitutive model because of their different behavior at elevated temperature and their frequent application in structures for which fire design is relevant. The material parameters in the model are calibrated with the experimental results of creep tests, carried out with cons...

Cryogenic and Elevated Temperature Strengths of an Al-Zn-Mg-Cu Alloy Modified with Sc and Zr
Metallurgical and Materials Transactions
; The effect of minor additions of Sc and Zr on tensile properties of two developmental Al-Zn-Mg-Cu alloys was studied in the temperature range -196 C to 300 C. Due to the presence of Sc and Zr in a fine dispersoid form, both low-temperature and elevated temperature strengths of these alloys are much
