摘要

试验探讨了利用热压-热挤压变形工艺

对AZ80镁合金切屑挤压成棒料再回用

制定了棒料的成型工艺。在压制坯料时

切屑温度为330℃

模具温度为350℃

压力为200MPa。挤压时

坯料温度及模具温度与压制坯料一致。挤压比为25∶1

挤压速度为20mm/s。回用棒料经过（200℃+8h）热处理后

σb为310MPa、σs为230MPa、δ为7%。探讨了AZ80镁合金切屑在热挤压变形成形后的微观组织和力学性能。

Abstract

AZ80 magnesium alloy rod was squeezed with reclaimed chip by means of hot press-hot extruded deformation

where chipping temperature is 330 ℃

die temperature is 350 ℃ and pressure is about 200 MPa during hot pressing while squeezing rate is 25 and squeezing velocity is 20 mm/s during squeezing castings.The tensile strength

yield strength and elongation of the reclaimed rod treated at 200 ℃ for 8 hours are 310 MPa

230 MPa and 7%

respectively.The microstructure and mechanical properties of hot extruded AZ80 magnesium alloy chip are approached.
