摘要

采用自制的振动频率可调的倾斜流变装置

制备了半固态合金浆料并直接进行了流变压铸

研究了振动频率对半固态ZL104合金组织及性能的影响。结果表明

利用带振动装置的倾斜板法制备半固态合金浆料并进行流变压铸

成形试样的组织细小

颗粒较为圆整

随着振动频率的增加

组织进一步细化。振动频率对抗拉强度和伸长率影响较大。随着振动频率增加

抗拉强度、伸长率、硬度和冲击韧度都在增加

当振动频率为40Hz时

抗拉强度为291MPa

伸长率为7%

硬度（HBS）为80.8

冲击韧度为0.95kJ/m2。

Abstract

Influences of vibration frequency on the microstructures and properties of semi-solid alloy ZL104 which was prepared and rheo-die casting by a self-designed inclined rheological experimental facility with adjustable vibration frequency were investigated.The results indicate that the microstructure of specimen formed is fine and round.With increasing in the vibration frequency

grain size in the microstructure is further decreased.Vibration frequency exhibits the key role in the tensile strength and elongation.With the increase of vibration frequency

the tensile strength

elongation

hardness and impact toughness of the specimen formed are increased.When the vibration frequency is 40Hz

the tensile strength

elongation

hardness and impact toughness reach 291MPa

80.8HBS and 0.95kJ/m2 respectively.
