半固态加工技术,历经40多年的研究和发展,对其认识愈来愈深入。开始,人们认为它仅仅是一种新颖的铸造加工方法,继而认为是塑性加工的延伸,且是锻造和铸造之间的一个加工链、金属加工的一种补充。后来在对铸、锻两种加工方法的发展轨迹研究基础上,惊奇地发现,半固态加工技术不仅是作为工艺方法的补充出现在金属加工领域中,而且是铸造、锻造工艺发展的一种必然。由于它加工的组织——球晶的存在,使其有“剪切变稀”的易充填特性,特别是最终加工组织呈细等轴晶类变形组织,而非枝晶,具有极好的力学性能,这是造铸和锻造所不具备的。最后,采用“材料质量利用率”和“材料性能利用率”这两个指标,比较了3种工艺方法,得出了深入开展半固态加工技术的研究和应用,是推进“节能减排”的最佳途径之一。随着时间的推移,其优势愈来愈彰显,并将为企业界所接受。 Semi-solid processing technology, after 40 years of research and development, its understanding more and more in-depth. Initially, it was considered as a novel method of foundry processing, then as an extension of plastic processing and as a processing chain between forging and casting as a complement to metal processing. Later on the casting and forging two processing methods based on the development of trajectory, based on the surprise found that semi-solid processing technology not only as a supplement to the process appears in the field of metal processing, but also casting, forging process development of a necessity . Because of its processing organization - spherulites exist, so that it has “shear thinning ” easy filling characteristics, especially the final processing organization was fine equiaxed grain deformation organization, rather than dendrite, with excellent Mechanical properties, which are not made and cast forging. In the end, compared with the two methods of “material quality utilization” and “material property utilization rate”, three methods were compared and the research and application of semi-solid processing technology in depth was promoted. Energy-saving emission reduction, "one of the best ways. With the passage of time, its advantages have become increasingly evident and will be accepted by the business community.
