                怎么确定7000系Al-Zn-Mg-Cu合金凝固过程中的共晶反应?

                2016-09-01技术资料

                7000系Al-Zn-Mg-Cu合金凝固过程中的共晶反应怎么确定,查相图还是怎么?

                我连完整的三元相图都没有见过,只见过三元相图的等温截面和变温截面(其实是相当于变相的二元相图)

                一般来说二元共晶反应通过二元相图确定??三元共晶反应查文广东体彩11选5走势图献
                ?
                是没有所以才问么,只能拿软件算某个广东11选5旺彩大师温度和成分下的相,但是无法确定共晶温度和广东11选五5走势图表产物。
