The results show that 610 ℃ is the key point of the temperature—viscosity relationship of aluminum foam. While the melt temperature is below 610 ℃, the viscosity elevates greatly with decreasing temperature. While melt temperature is above 610 ℃, the viscosity elevates slowly with decreasing temperature. The uniform of foaming agent is improved with increase of melt temperature, stirring speed and dispersing time. However, the aggregation of TiH2 still exists stirred at rotation speed 3000 r/min for 30 s. Three approaches are found to be effective to improve the uniform of TiH2 in the melt route precursor: disperse TiH2 in the viscosity-temperature non-sensitive area of aluminum alloy, density the cast precursor by pressing, and use a rotation speed higher than 3000 r/min.
结果表明，610 ℃是ZLD104合金熔体粘度变化的转折点，低于610 ℃熔体粘度随温度的变化较大，高于610 ℃熔体粘度随温度的变化较小；随分散温度、搅拌速度、分散时间的提高，发泡剂分散均匀性提高，但在3 000 r/min，分散30 s的条件下，发泡剂的团聚现象仍然存在；在粘度温度非敏感区分散发泡剂，并采用挤压使发泡先驱体致密化，以及采用3 000 r/min以上的搅拌速度分散发泡剂，可提高熔体路径发泡先驱体发泡剂均匀性。
