中文摘要：
首先简介了热态内压成形国内外研究现状，然后重点介绍了哈尔滨工业大学在热态内压成形装置和镁合金热态内压成形方面的研究进展。所研制的热态内压成形装置可在一定温度下实现镁舍金大膨胀率变径管、弯曲轴线变截面管的研制。采用AZ31B镁合金管材获得膨胀率30％，最大减薄率6．7％的变径管件；采用AZ61A镁合金管材试制了正方形截面件和某轿车样件，采用AZ31镁合金管材试制了截面带有小圆角的管件。介绍了上述样件的工艺过程，表明镁合金热态内压成形工艺具有广阔的应用前景。
英文摘要：
State of the art in warm hydroforming is introduced first. Then, research development of Harbin Institute of Technology （HIT） is described, including warm hydroforming instrument and Magnesium alloy warm hydroforming processes. The warm hydroforming instrument developed by HIT is available for R＆D of Mg-alloy tubular parts with multiple diameters and high expansion ratio and parts with bent axis and various cross sections. An AZ31B part with the maximum expansion ratio of 30% and the maximum thinning ratio of 6.7% has been formed. By using of AZ61A, a part with square cross-section and a automotive sample part have been manufactured. In addition, a AZ31 part with small corner radii on cross sections is formed. The processes for the parts mentioned above are introduced and show that warm hydroforming of Magnesium alloy has prospective applications in future.
