通过晶内铁素体的析出细化了晶粒，提高了钢的强度与韧性。
时效态合金在焊核区晶内析出的第二相明显要多于固溶态。
储层的主要孔隙空间为粒间溶孔、粒内溶孔、铸模孔和裂缝。
1·For the alloy, the dominant mechanism of superplastic deformation is that the boundary sliding process will be accompanied by intragranular dislocations.
位错攀移越过弥散质点的过程是合金超塑变形的速控过程，超塑变形的主要机制是晶界滑移伴随晶内位错运动。
2·The amount of intragranular precipitates in the age treated alloy were more than that of the solution treated alloy.
时效态合金在焊核区晶内析出的第二相明显要多于固溶态。
1·The catalyst intragranular state for methanation system, which is a parallel reaction of equilibrium-restrained, was studied.
