To break down the eutectic carbide network of A-cast structure with grain size 4-5 grade, tensile strain of 60% is needed.
当铸志晶粒度力4 ~ 5级寸，破碎晶炭化物组织需要有60%以上的拉应变。
The stable eutectic carbides with complex morphologyprevent coalescence of grain boundary voids and therefore prolong tertiary creep stage and rupture time.
在晶界上形成形态复杂稳定的碳化物能阻止空洞的连接，从而延长了蠕变第三阶段，增加了断裂时间。
The eutectic played a role in inhibiting grain growth during casting.
这类共晶组织在合金的铸造过程中起抑制晶粒长大的作用。
