查询词典 coarsened

When the precipitate is not yet coarsened as shorter in rupture life, the precipitation hardening effect may be intensified by the increasing of precipitate, so that the high temperature strength may be raised by the increase of W content, while the precipitate may coarsen markedly and the precipitation hardening effect may reduce on heating for sufficient long time.

在持久寿命较短时，析出相来不及粗化，析出量的增加造成了析出强化效果的加强，即钨量的增加提高了高温强度；而当长时间加热后，析出相发生了明显的粗化，降低了析出强化效果。

为揭示贝氏体相变机制及外加应力对它的影响，采用透射电镜研究了140MPa的外加拉应力对中碳低合金钢35MV7的450°C等温贝氏体相变组织形貌的影响。

The intermetallic compounds are coarsened into nubbly Cu6 Sn5 phase by adding excessive Cu into Sn-Cu solder alloy. For Sn-9Zn-xCu solder alloys, the long needle-like Zn rich phase which is the mainly existing form of Zn in Sn-Zn solders is transformed into Cu5 Zn8 phase and fine Zn rich phase by the addition of 2% Cu, while CuZn phase and Cu6 Sn5 phase are formed in Sn-9Zn-10Cu bulk alloy. When soldering within short time under 260℃, the ripening and growth of IMC at Sn-xCu/Cu interface are accelerated with increasing Cu content in Sn-Cu solders.

结果表明，当Sn-Cu钎料中Cu的含量为2%时，基体中IMC粗化为块状的Cu6Sn8相；对于Sn-9Zn-xCu钎料合金，2%Cu元素的加入使得Sn-9Zn基体中长针状的富Zn相转化为Cu5Zn8相以及细小的富Zn相，而当Cu含量达到10％时，钎料基体中的IMC为CuZn相与Cu6Sn5相。

Firstly, the specific surface area of nano-coated particle is much larger than that of ordinary wollastonite, and the edges formed in comminuting is passivated, which made the slippy crystal surface coarsened. At the same time, the color of nano-coated particle became whiter, which fit for light ware. Secondly, if the coated wollastonite hasn't been modified by coupling agent, the toughness of PP/ wollastonite composite couldn't be improved.

在硅灰石表面包覆上纳米级SiO2小颗粒对硅灰石的应用特性有重要影响：①纳米包覆粒子填料的比表面积比普通硅灰石大，纳米级SiO2小颗粒钝化了由于机械力粉碎造成的硅灰石的棱角，使其平滑的晶体解理面变得粗糙，同时硅灰石粉体白度增大，可应用于浅色制品。

The results show that the grain is not coarsened and the cavity rate is less than 1.5%.

结果表明，成形零件的微观组织无明显粗化，其孔洞率小于1.5%。

I have not entirely returned, i know, having been changed by time and place, coarsened by problems estranged by absence.

我还没有完全回来，我知道，已经改变了时间和地点，由粗大的问题日渐疏远的缺席。

Homogenization treatment before the extrusion coarsened the grain size and reduced the tensile strength and yield strength.

挤压前均匀化热处理使挤压态合金的晶粒尺寸粗化，拉伸强度和屈服强度降低。

Heat sintered ZrO_2 ceramic does not react with any acids and bases except HF. It can't be coarsened by the traditional pretreatment process. Through a great deal of experiments, author found a kind of coarsened prescription which can corrode ZrO_2 ceramic, forming many holes and troughs on its surface.

高温烧结后的ZrO_2陶瓷的化学稳定性很高，除HF外不溶于任何酸碱，传统的粗化液对它没有粗化作用，笔者通过大量的实验，找到了ZrO_2陶瓷粗化液的配方，它能在ZrO_2表面腐蚀出大量均匀的微坑和凹槽。
