But the refinement effect of Ti-B is better then that of RE,the roundness of the globular grains obtained is better,the spheroidization velocity of the primary α-Al grains is faster.
但钛硼细化效果比稀土好,获得的球形晶粒的圆整度高,初生α-Al晶粒的球化速度快。
The experimental result shows that RE can refine the globular grains of semisolid Al-alloy remarkably,improve the roundness and uniformity of globular grains.
结果发现:稀土显著细化了半固态铝合金的球形晶粒组织,并提高了球形晶粒的圆整度和均匀性。
