zone-purified metal

In the tensile test, fracture appears in the heat affected zone of aluminum base metal, and its tensile-strength is 72.09 MPa.

在进行拉伸试验时，断裂发生在铝母材的热影响区，接头强度为72.09MPa。

A simulated test on distribution characteristics for heavy metal particle sizes in the mixing zone of fresh and salty water

咸淡水交汇区重金属粒径分配特征的模拟实验

But when the Φ value is higher, as the Φ increases, τ is hardly altered. In the process of squeeze cast particles reinforced metal matrix composites, the temperature equilibrium equations of infiltration zone were established and solved.

但当Φ值很大时，Φ的升高使τ＊的减少不明显.建立了挤压铸造MMCs过程中液态金属浸渗区和未浸渗区的温度平衡方程，并求出了差分解。

The metal flow of slab in sizing was analyzed and the buckling and "fish tail" at slab head and end were studied with plastic collapse theory according to the mutual influence of end and deformation zone.

对减宽侧压过程的板坯金属变形流动情况进行了分析，并结合外端与变形区的相互影响，采用塑性失稳理论对板坯的失稳弯曲现象和头尾部鱼尾变形进行了研究。

It is found that the fluctuation is induced by the gradual aggravation of thermal expansion and thermal softening, and is closely related to the evolution of plastic zone in the metal material.

根据激光静态加热过程中应力出现的波动现象，发现是热膨胀、热软化逐渐加剧导致的，且与金属板内部塑性区域的发展演化密切相关。
