【摘要】：研究了不同軋制變形量和軋制速度對(duì)AZ31鎂合金板材微觀組織和力學(xué)性能的影響。軋制變形可顯著細(xì)化AZ31鎂合金板材的晶粒尺寸并提高其綜合力學(xué)性能。當(dāng)軋制速度為5 m/min,軋制變形量為50%時(shí),板材平均晶粒尺寸最細(xì)可達(dá)到9μm,其抗拉強(qiáng)度、屈服強(qiáng)度和延伸率分別提高到280、180 MPa和30%以上,同時(shí)探討了AZ31鎂合金屈服強(qiáng)度與晶粒大小之間的關(guān)系。在大量AZ31鎂合金軋制文獻(xiàn)數(shù)據(jù)和本實(shí)驗(yàn)一系列數(shù)據(jù)的基礎(chǔ)上,對(duì)比分析了不同軋制工藝對(duì)AZ31鎂合金綜合力學(xué)性能的影響。研究表明,本實(shí)驗(yàn)所采用軋制工藝可顯著提高AZ31鎂合金板材的綜合力學(xué)性能,同時(shí)降低板材軋向(RD)和橫向(TD)的各向異性。
[Abstract]:The effect of different rolling deformation amount and rolling speed on Microstructure and mechanical properties of AZ31 magnesium alloy sheet is studied. Rolling deformation can significantly refine the grain size of AZ31 magnesium alloy sheet and improve its comprehensive mechanical properties. When the rolling speed is 5 m/min and the rolling deformation amount is 50%, the average grain size of the plate can reach 9 m, and its resistance is up to 9. The tensile strength, yield strength and elongation increase to 280180 MPa and 30% respectively. The relationship between yield strength and grain size of AZ31 magnesium alloy is discussed. On the basis of a large number of AZ31 magnesium alloy rolling documents and a series of data in this experiment, the effects of different rolling processes on the comprehensive mechanical properties of AZ31 magnesium alloys are compared and analyzed. The study shows that the rolling process in this experiment can improve the comprehensive mechanical properties of AZ31 magnesium alloy sheet and reduce the anisotropy of sheet rolling (RD) and transverse (TD).
