In modern industries, such as aerospace, automotive, marine and others, aluminium magnesium alloys are the most frequently used non-ferrous materials. This paper discusses optimising processing factors to produce a high hardness of dissimilar Al/Mg alloys. The experiment was designed conducted by varying input according response surface methodology-central composite design. regression model has...

Magnesium alloy, copper and other light alloys are widely used in aerospace, new energy vehicles, lightweight manufacturing fields due to their excellent mechanical properties, but the connection between has always been a challenge. Ultrasonic welding is an advanced technology that can realize high-strength heterogeneous alloys. In this study, ultrasonic AZ31B magnesium pure carried out. The fr...

To solve the edge crack problem of AZ31B magnesium alloy cold rolling, a strong pulsed electric current was introduced to rolling process. The influence intensity, frequency, width and other parameters on cracking plate analyzed based principle single variable. According experimental results, assistance cut down inhibition effect increased obviously with larger parameters. When reached 4800 A, ...
