Engineering Faculty Internships: Development of Efficient Semi-Solid Production Processes for Aluminum Alloys

卡斯纳9413131这项研究是为了开发一种高效的铝合金球化工艺。将开发特定的加热工艺和循环、成分和成型操作，以实现由成本和最终材料性能决定的球化半固体的有效生产和制造。传统的金属成形工艺，如铸造和锻造，可以使用新型的半固态合金，在成本和可靠性方面得到显著改善。然而，只有对半固态进行特殊处理以确保球化组织，才有可能做到这一点。具有典型树枝状固相形态的半固态由于开裂而不容易成形。到目前为止，在商业规模上生产球状微结构一直很困难。这项研究针对半固态在铝合金铸造中的应用。降低铸造厂的浇注温度是一个有价值的目标。制造工艺的开发是铝业和大学共同努力的结果。这项工作的商业潜力很大。

Kassner 9413131 The research is to develop an efficient spheroidization technology for several aluminum alloys. Specific heating processes and cycles, compositions, and forming operations will be developed that allow effective production and fabrication of spheroidized semi-solids as determined by cost and final material properties. Traditional metal shaping processes such as casting and forging can be dramatically improved in terms of cost and reliability using novel semi-solids alloys. However, this is possible only with special processing of semi-solids to ensure a spheroidized microstructure. Semi-solids with a typical dendritic morphology of the solid phase cannot be readily shaped due to cracking. To date, producing a spheroidized microstructure on a commercial scale has been difficult. The research is directed at the use of semi-solids in the casting of aluminum alloys. The reduction of casting temperatures in foundries is a worthy goal. The manufacturing process development is a collaborative effort between an aluminum industry and the university. The commerical potential of the work is high.
