Among the grain refiner , the mixture had the best grain refmering performances 其中以混合物作为细化剂时效果最好。
The result showed that after adding grain refiner , the hardness of magnesium alloys changed little while the impact toughness increased 结果表明,添加细化剂后,镁合金的硬度变化不大,而冲击韧性提高。
A : last , the mechanical characters of materials with refined structures are tested . it proves that both plasticity and the strength are improved 最后对获得的细晶材料进行力学性能(抗拉强度、抗压强度和延伸率)测试,与未加细化剂的合金进行比较,证明塑性和强度都有所提高。
As being applied to production can save raw material and reduce cost . the experiment prosposes al - ti - b - re master alloy and theoretical analyses know that it can overcome some weakness of al - ti - b master alloy and belongs to ^ a grain refiner needing studied further 试验还提出了aitibre中间合金,理论分析表明,它能够克服aitib中间合金的一些缺陷,是一种有一待于我们进一步深入研究的细化剂。
