| Abstract: | The slurring and the structure evolution mechanism of near-liquidus casting method arediscussed,and the method is compared with other semi-solid moulding methods,and the effect of variable parameters on near-liquidus technology are reviewed.The research status and the latest achievements of the near-liquidus casting method and the existed problems are introduced from the nonferrous metals to high melting point alloy steels.Finally,the prospect of near-liquidus moulding technology is proposed. |
