    摘要:

    制備了Al6.2Zn2.3Mg和Al5.0Zn3.0Mg兩種合金并進(jìn)行了固溶時(shí)效處理,基于EET理論,計(jì)算了合金基體固溶體的價(jià)電子結(jié)構(gòu),研究了Zn/Mg對合金時(shí)效析出行為的影響。研究認(rèn)為：Al6.2Zn2.3Mg合金固溶時(shí)優(yōu)先形成的a-Al-Zn-Mg固溶體為η相析出序列GP區(qū)的形成提供了條件,合金只啟動η相析出序列,故時(shí)效硬化行為表現(xiàn)出明顯的雙峰特征；而Al5.0Zn3.0Mg合金固溶時(shí)形成的a-Al-Zn-Mg和a-Al-Mg-Zn-Mg-Al兩種固溶體分別為η相和T相析出序列GP區(qū)的形成提供了條件,合金時(shí)效時(shí)同時(shí)啟動了時(shí)效進(jìn)程不同、強(qiáng)化相析出與轉(zhuǎn)變時(shí)間及其強(qiáng)化作用不同的η相和T相兩個(gè)析出序列,故Al5.0Zn3.0Mg合金時(shí)效硬化雙峰特征不明顯。

    Abstract:

    Al-6.2Zn-2.3Mg and Al-5.0Zn-3.0Mg alloys were prepared, and then solution-aging treatment proceeded. Based on the empirical electron theory of solids and molecules (EET), in this paper, the valence electron structures of solid solutions of alloys were calculated, and then the effect of Zn/Mg on aging-precipitation behavior of Al-Zn-Mg alloys was studied. It is shown that solid solution a-Al-Zn-Mg prior formed during solid solution of Al-6.2Zn-2.3Mg alloy provides the condition for the formation of GP Zone of h precipitation sequence. Only h precipitation sequence is started, so aging-hardening behavior of Al-6.2Zn-2.3Mg alloy appears obvious two peaks characteristic. While the two solid solutions a-Al-Zn-Mg and a-Al-Mg-Zn-Mg-Al formed during solid solution of Al-5.0Zn-3.0Mg alloy provide the condition for the formation of GP Zone of h and T precipitation sequence, respectively. These two precipitation sequences have so many different at aging progress, precipitation time and their strengthening effects of strengthening phases, transforming time and caused strengthening effects weakness of strengthening phases, so these two precipitation sequences of h and T are started when aging, aging-hardening behavior of Al-5.0Zn-3.0Mg alloy does not appears obvious two peaks characteristic.
