【 摘 要 】

Lack of technology for the production of large inexpensive feedstock, with uniform spherical primary phase throughout as required for semi-solid forming, has restricted realization of the full potential for the semi-solid forming process. Furthermore narrow process windows and alloy chemistry restrictions increase process costs and limit performance attributes possible with existing semi-metal systems. Successful semi-solid forming trials utilizing Chesapeake Composites Corporation's DSC{sup TM} Metals for feedstock indicate that this represents a generic approach to providing a permanent highly uniform, spherical solid phase, without electromagnetic or mechanical shearing. This approach also provides for further growth of semi-solid forming by providing for: low cost large diameter billet stock, reduced semi-solid forming costs, extension of semi-solid forming to new alloy systems, and semi-solid formed components with substantially enhanced physical and mechanical properties.
