Mg-Alloy Formability in Deep Drawing

概要

論文の詳細を見る
The formability of magnesium alloy AZ31 was studied through uniaxial tensile test and deep drawing test at elevated temperature. Effects of the working enisotropy and temperature on mechanical properties were investigated. Tests were made at room temperature then at 160,180,200 and 220℃. Specimens were oriented 0ﾟ,45ﾟ and 90ﾟ to the rolling direction. Cylindrical deep drawing tests were done for the same temperatures in order to clarify the effects of the processing parameters on formability(e.g.temperature,punch speed,lubricant and blank-holder pressure). Experimental results show that the effects of anisotropy tend to decrease when temperature increases. Formability improvements are observed for temperature above 200℃. Finally,the highest drawing speed is achieved for an opetating temperature of 200℃.
