利用TEM,在低成本粉末锻件第二批试样中观察到了γ'相对位错滑移的钉扎作用,发现视野内所有γ'相在位错切过以后内部形成非常多的层错
Using TEM, the pinning effect of γ' relative dislocation slip was observed in the second batch of samples of low-cost powder forgings, and it was found that all γ' phases in the field of view formed a lot of stacking faults after dislocation slipping.
