[交流] 【讨论】thermo-calc软件安装后如何获得相图？

thermo-calc软件安装后如何获得相图？不知道各位是否用过这个软件，安装后，按照相关示范步骤来但是并不能获得输入化学成分钢种的相图。请问有谁懂的，指教下。

liverangel(金币+2,VIP+0):谢谢你的例子， tcfe3是商业数据库，盗版数据库一般没有它的licensence 12-22 00:24

我们目前见到的相图一般为三元相图，元数再多只能固定几相，让三相可变，计算，再变化固定相的量，再算。钢的成分太多，都作为变量不可能有相图，算出来只能有一个平衡组成（包括元素和化合物），当然还与你用的t ...

In some databases there are ‘alloys’’ predefined. An alloy has a

上述下划线部分为重点，其中Database /SSOL/: tcfe3 中数据库 /SSOL/在程序中出不来，不知道是不是我的软件里没有还是怎么回事，按这个说明应该是可以进行多元合金的相图计算。其中x轴为C含量变化，Y轴为温度。其余元素都固定。
我怀疑是我的数据库不全，不过要是各位有谁更了解这个软件，也许能指点再下一二。这里先谢谢了！
