查询词典 refined grain

The results showed that the second phase was refined and distributed dispersedly in the matrix of the alloy after ECAE. The refined particles could cut the soft matrix, which was useful to grain refinement during ECAE. The dispersoid distribution of the second phase could strengthen the matrix and improve mechanical properties of the alloy.

The results showed that Nd2Fe14B grain refined quickly and the grain size of α-Fe decreased while increasing milling time.

结果表明：延长球磨时间，Nd2Fe14B相迅速细化形成非晶，α-Fe的晶粒尺寸逐渐减小，25h后趋于定值（约为7nm）。

The grain shape of Co change to equaxial fine grain and refined by adding of Al2O3 powder.

SEM的表面型态中，未添加Al2O3皆发现等轴状细晶，在添加Al2O3后，成核点数目变多，晶粒会随著添加量增加而减小。

With decreasing the grain size of austenite before the phase transformation, the transformed ferrite fraction is increased and the final grain size is refined.

在应变、过冷提供相变驱动力的条件下，相变前奥氏体晶粒尺寸对于铁素体微观结构的形成有着重要的影响。

It is shown that both strength and delayed fracture resistance of 42CrMoVNb steel increase when its grain size is refined from 20 m to 4 m, but they do not increase when refined to 2 m.

结果表明，随着晶粒细化， 42CrMoVNb钢的强度和缺口拉伸延迟断裂抗力逐渐提高；但当晶粒细化到2 m时，强度和延迟断裂抗力均不再提高。

The results show that the grain size is refined by the addition of Nd or Dy, especially combined addition is better than single addition. With the addition of 0.2 % Nd and 0.6% Dy, the grain size is reduced from 150 μm to 60 μm. Combined addition with two rare earths elements makes the tensile strength, yield strength and elongation of ZK10 alloy increase to 191.0 MPa, 69.0 MPa, and 16.6%, increasing by 89%, 43%, 232% respectively, compared with ZK10 alloy without RE element.

结果表明：ZK10镁合金中分别加入Nd和Dy均能细化晶粒，且Nd和Dy同时加入的效果优于单一加入的效果，当同时加入质量分数为0.2% Nd和0.6% Dy时，合金的平均晶粒尺寸由原来的150 μm细化至60 μm，使ZK10合金的抗拉强度和屈服强度分别提高至191.0 MPa和69.0 MPa，伸长率达到16.6%，与未加入稀土的ZK10合金相比分别提高89%，43%和232%。

Besides, the dendrite and the boride morphology in the big grain and small grains are same. All these results show that the boron addition does not influence the solidification process, but promote the β→α transformation, so still grain refined lamella can be gained at last.

这些实验结果表明：硼化物对Ti46Al8Nb基合金晶粒的细化作用主要不是通过改变 L →β的凝固过程得到的，而是通过影响凝固后的β→α固态相变来实现的。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.
