Effect of texture on acoustic emission produced by slip and twinning in AZ31B magnesium alloy

The acoustic emission (AE) detected during the fatigue process in an as-rolled magnesium alloy AZ31B was analyzed. Measurements were made during fatigue in air as well as in aqueous 0.1% NaCl solution. Three stages of fatigue were detected with AE. It is concluded that plasticity, crack extension or friction was the main AE sources during fatigue.

Different Levels

In this investigation an attempt has been made to study the effect of welding on fusion characteristics of pulsed current gas tungsten arc welded AZ31B magnesium alloy joints. Five joints were fabricated using different levels of welding speed (105 mm/min –145 mm/min). From this investigation, it is found that the joints fabricated using a welding speed of 135 mm/min yielded superior tensile properties compared to other joints. The formation of finer grains and higher hardness in fusion zone and uniformly distributed precipitates are the main reasons for the higher tensile properties of these joints
