This structure has the added benefit of lacking the grain boundaries that most metals have.

它没有晶粒边界，大多数有晶粒边界。

Those are weak spots where the material is more susceptible to scratches or corrosion.

晶粒边界是大多数容易被刮破的脆弱的地方，这些地方也容易被腐蚀。

You can seed it with more cold chocolate so you can chop up chocolate, put more cold chocolate in.

你可以加入晶粒物质使更多的巧克力冷凝，这样你就可以把巧克力切碎，放更多的冷巧克力进去。

It just has larger and more crystalline grains.

它只是具有更大和更多的晶粒。

So because the energy levels are high, the grain size is coarser.

因此，由于能量水平较高，晶粒尺寸较粗。

The superstructure is made of a torsion-resistant welded structure fabricated from high strength fine grained structural steel.

上部采用高强度细晶粒钢制成的抗扭焊。

When the temperature reaches 300 and 400, the deformation inside the grains becomes much more uniform.

当温度达到300至400时，晶粒内部的变形变得更加均匀。

As the temperature increases to 200, we observe that the number of slip traces inside the grains seems to increase.

随着温度升高到200℃，我们观察到晶粒内部的滑移线数量似乎增加了。

So, I've been trying to find and establish an intermediate experimental and characterization method to describe the strain localization behavior at the sub-grain scale.

因此，我一直在努力寻找并建立一种介于实验与表征之间的方法，以描述亚晶粒尺度下的应变局部化行为。

In some grains, we can observe wavy slip characteristics To make it clearer, I selected a few lines inside the grains and performed trace analysis.

在一些晶粒中，我们可以观察到滑移特征呈波状。为了更清楚地说明，我在晶粒内部选取了几条线并进行了痕迹分析。

First, at room temperature, we can see that the deformation inside the grain is mainly concentrated along a few slip traces, showing characteristics of planar slip.

首先，在室温下，我们可以看到晶粒内部的变形主要集中在几条滑移线上，表现出平面滑移的特征。

In some grains, we even observe wavy slip characteristics To make this phenomenon clearer, I selected a few line segments inside the grains and performed trace analysis This image shows the strain variation along a specific line segment at different temperatures.

在某些晶粒中，我们甚至观察到波状滑移特征。为了更清晰地展示这一现象，我在晶粒内部选取了几条线段进行痕迹分析。此图展示了在不同温度下沿特定线段的应变变化情况。
