查询词典 base metal

Overheating can result in overtempered martensite or untempered martensite formations in the base metal.

过热会造成在本体金属中形成过回火马氏体或者欠回火马氏体。

The Flex-Hone process is a low-temperature, low pressure abrading process that exposes the undisturbed base metal structure to produce a long wearing surface.

球头刷处理的整个过程是以一套低温低压的研磨系统将原状的基础金属结构展现出来以产生持久耐用的表面。

We find that the proportion of the contribution of the three factors on the fatigue strength improvement of the peened joints depends on the base metal static strength.

结果表明：超声冲击处理提高焊接接头疲劳强度的硬化，改善焊趾几何外形和在焊趾区形成表面压应力三者贡献的大小，与被处理焊接接头的母材静强度有一定的相关性。

Seam welded C276 alloy heat exchanger tubing to UNS N10276 is allowed providing the tube weld is not peened or bead worked, but the whole tube in both weld and base metal is cold drawn, bright annealed and passivated and is to ASTM B626 Class III specification.

如果管子焊缝不是peened or bead worked，则使用焊缝缝焊接式C276合金换热管(UNS N10276)是允许的，但是焊缝和基金属上的整个管子是冷拔的、光亮退火和钝化的，并应符合规范ASTM B626 Class III上的规定。

The root pass must properly fuse to the base metal and the tack welds..

根部焊道必须和母体金属与点焊充分结合到一起。

This then allows the electrode negative portion of the cycle (where the current flows from the tungsten into the work) to melt the base metal and fuse the join.

这就使负电极部分的周期(如从目前的流动纳入钨工)、熔断器熔化金属基地的投入。

Meanwhile, as the growth of arc, the lost of arc heat quality becomes larger, so the heat quality which is used to fuse base metal and weld stick decreases, the weld width and weld reinforcement decreases comparatively.

同时，电弧增长后，电弧的热量损失加大，所以用来熔化母材和焊丝的热量减少，相对焊缝宽度和余高就略有减少。

Generally in accordance with the strength of steel grades in the selection of the appropriate electrodes, but also need to weld steel, base metal composition of the transition, welded structural dimensions.

一般依钢材的强度等级来选用相应的焊条，同时还需要钢材焊接性，母材成份的过渡，焊接结构尺寸。

Since 1982, the Mint began making copper-coated zinc(9) pennies to prevent metals speculators from taking advantage of lofty(10) base metal prices.

1982年后，造币厂开始发行铜衣锌币来避免投机商从中牟利。

The result of SSRT showed that the tensile strength in fusion zone of LBW weldment is higher than base metal, and the IGC in weld decay zone did not crack because of the stretch;IGC in fusion zone of GTAW weldment leads to early fracture, and the IGC in weld decay zone clearly stretched and cause the material to crack. Intergranular stress corrosion cracking in this section is still possible.

慢应变速率拉伸试验结果，LBW焊件之焊道强度高於母材，且於焊接衰化区所造成之沿晶腐蚀并未因拉伸造成开裂；GTAW焊件的焊道沿晶腐蚀导致断裂提早发生，且在焊接衰化区的沿晶腐蚀明显拉伸造成开裂情形，仍有在此区域发生沿晶应力腐蚀破坏的可能。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
