摘要: 在Couette型同軸圓桶流變儀上,采用滯后環工藝研究了半固態AlSi6Mg2鋁合金漿料的觸變行為.實驗結果表明半固態AlSi6Mg2鋁合金漿料在循環剪切變形下,靜置時間越長、剪切速率到達最大值所用時間越短、固相分數越大、最大剪切速率越大,則合金漿料τ-γ.滯后環所包圍區域面積越大,合金漿料的觸變性越強.

Abstract: The hysteresis loop technique was applied to investigate the thixotropic behavior of semi-solid AlSi6Mg2 aluminum alloy slurries using a Couette type viscometer. The experimental results show that, under cyclic shear deformation, the thixotropy degree of semi-solid AlSi6Mg2 alloy increases with increasing resting time, solid fraction, maximum shear rate, and decreasing time to reach the maximum shear rate.
