Abstract
The paper is aimed to investigation of mechanical properties and microscopic fracture features of the superlight high-strength alloy of an Al-Cu-Li system and its welded joints as a function of temperature (293-20K) and orientation with respect to rolling direction.
It is found that the strength properties and the plasticity of the alloy and its welded joints are appreciably dependent on temperature, and the elastic modulus is also sensitive to sample orientation.
The scanning electron microscopy is used to perform fractographic study into the fracture character of the basic material and its welded joints under the above test conditions. The correlation between the macroscopic plasticity of the material, the fracture micromorphology and the complicate structure-phase state is considered.
