球状初晶半固态金属或合金浆料直接成型方法及装置
摘要：
一种球状初晶半固态金属或合金浆料直接成形方法及装置，涉及半固态金属或合金浆料的直接成形，特别涉及半固态金属和合金浆料的流变成形。将低过热度即过热5～30°K的金属或合金液浇入一铸模即承接容器中，同时对该过热金属或合金液施加一弱搅拌力即低功率搅拌力，得到球状初晶半固态金属或合金浆料；该球状初晶半固态金属或合金浆料经过进一步冷却或保温，使该球状初晶的半固态金属或合金浆料冷至特定的温度或固相分数，该温度高于该金属或合金的平衡固相线温度或不低于该金属或合金半固态浆料的直接成形温度，在该冷却或保温过程中，该金属或合金半固态浆料中的球状初晶得到进一步的圆整优化；将该圆整优化后的球状初晶半固态金属或合金浆料送至压铸机或锻造机的射室进行半固态浆料直接成形，其优点在于降低能耗，缩短工艺流程，降低铸件或成形件的成本。
摘要（英）：

The direct forming method of spherical primary crystal semi-solid metal or alloy sturry material includes the following steps: pouring low overheated metal whose overtemperature is 5-30 deg.K or alloy solution into a casting mould, i.e. receiving container, at the same time applying a low-power stirring foce to the overheated metal or alloy solution to obtain spheircal primary crystal semi-solid metal or alloy slurry, further cooling said semi-solid metal or alloy slurry and heat-insulating, and cooling to specific temp. or solidus fraction, in the course of cooling or heat-insulation said spherical primary crystal in the metal or alloy semi-solid slurry can obtain further round optimization, then feeding the round optimized spherical primary crystal semi-solid metal or ally sturry into the press-casting machine or forging machine to implement direct forming.
