    摘要:

    研究了顯微組織和應(yīng)變速率對(duì)全層狀Ti-47Al-2Cr(at%)合金室溫拉伸性能的影響，結(jié)果表明，全層狀TiAl基合金的室溫拉伸強(qiáng)度和室溫延伸率隨晶團(tuán)尺寸和層片間距的減小而提高；其室溫拉伸強(qiáng)度隨應(yīng)變速率的加快而提高；而應(yīng)變速率對(duì)其室溫延伸率的影響與顯微組織相關(guān)，低延性全層狀TiAl基合金的室溫延伸率對(duì)應(yīng)變速率不敏感，而高延性全層狀TiAl基合金的室溫延伸率對(duì)應(yīng)變速率敏感，并隨應(yīng)變速率的加快而提高。

    Abstract:

    The effects of the microstructure and the strain rate on the room temperature tensile properties of Ti 47Al 2Cr(at%) with fully lamellar microstructures were investigated. It is shown that the room temperature tensile strength and ductility increase with the decrease of colony size and lamellar spacing. The room temperature tensile strength increases with the increase of strain rate. The room temperature ductility of low ductility alloy is not sensitive to strain rate, but the ductility of high ductility alloy is sensitive and increases with the increase of the strain rate.
