Research which creates a heat-resistant Magnesium alloy into material with high toughness using a continuation ECAP micro-machining method with six axes.

为了检查连续加工时的挤压形式，提高力学性能，采用6轴ECAP法对AC4CH铝合金铸件进行挤压。当施加背压时，由于快速压降而产生的空隙被抑制了。结果表明，在半固态材料中，拉伸强度的提高是显著的。此外，连续进料是可能的形状被挤压到足够的下一关。结果，通过半固态铸造保持了变形，并通过添加ECAP方法提高了材料的强度。

In order to check the extrusion form at the time of continuation processing and improve the mechanical properties, the AC4CH aluminum casting alloy was extruded by the 6 axes ECAP method. When back pressure was applied, generating of the void due to a rapid pressure drop was suppressed. As a result, the improvement in a tensile strength was remarkable at semi-solid material. Furthermore, a continuous feeding is possible for the shape by which was extruded enough to the next pass. As a result, the distortion was maintained by the semi-solid casting and creation of the material whose strength improved by the addition to ECAP method was attained.
