Reduction pretreatment (RP) process, which is implemented after the billet is completely solidified, is an alternative p......

The micro-porosity is usually present in the as-cast microstructure,which decreases the tensile strength and ductility a......

In this work,alpha(α)brass was poured in green sand mould and metallic chill mould at about 1050℃. Sand casting method......

在镁合金中添加适量的Sr,不仅可以降低过冷度,且易吸附在固/液界面的前沿形成富Sr的吸附膜,降低晶粒生长速度,从而细化晶粒.细小的......

通过对超声波发生器的优化，研究了高功率超声波对7050铝合金铸锭中显微疏松形成的影响。试验结果表明，高功率超声处理的铸锭的组织更......

研究了一种含Re为4.0%～5.5%（质量分数）的实验型镍基单晶高温合金在不同定向凝固结晶条件下铸态的宏微观组织特征,分析了凝固结晶温度......

Y油田低电阻率油层测井、录井、岩心及试油等资料研究结果表明,其低电阻率油层成因主要是由于岩性较细、泥质含量较高,导致储集层......

通过传振工具杆对铝熔体进行超声振动处理,探讨了不同的超声功率对7050铝合金铸锭中显微疏松形成的影响。结果表明,经超声处理的铸......
