Influence of Retrogression Time on Mechanical Properties and Microstructure of 7150 Aluminum Alloy

The influence of the retrogression time on properties and microstructure of 7150-T77 aluminum alloy was studied by hardness testing, tensile property testing, exfoliation corrosion test and TEM. Results indicate that the matrix precipitated <i>η</i>' phase re-dissolves first, and th...
