The Hammer-Blow plate and rim are made of tough, shock resistant ductile iron to withstand heavy, valve releasing impact.

锤击轮盘和链轮由坚硬、抗冲击的球墨铸铁制成,能够承受沉重的阀门所产生的撞击。

The purest gold is the most ductile .

纯金最韧(大丈夫能屈能伸)。

The change from granite to foliated granite is transitional and there is no discontinuity between them. I think this foliated belt is a ductile shear zone.

从花岗岩到片理化花岗岩的变化是逐渐过渡的,二者之间不存在不连续面。我认为这个片理化岩带是一个韧性剪切带。

Characteristically, metals are opaque, ductile , and good conductors of heat and electricity.

从特点来看,金属不透明,有韧性,是热和电的良导体。

Brittleness. This property is the opposite to toughness. Brittle materials may resist a steady force, but fail easily when subjected to a sharp blow. Brittle materials are neither ductile nor malleable. Hard materials are usually brittle.

脆性这个性质与韧性相反。脆性材料可以抵受稳定的受力,但当受到猛烈的冲击时,很容易破坏。脆性材料既无韧性又无可锻性。硬的材料通常是脆性的。

The nodules of carbon are, in large part, what give ductile iron its exceptional ductility and shock resistance.

大部分球状碳,使球墨铸铁具有特别的人性和抗冲击性。

When a ductile material is tested, the reduction in cross-sectional area due to waisting causes an increased stress without an increased force, to ensure that extension proceeds uniformly.

当韧性材料被测试时,由于颈缩使横载截面面积减小,以至在受力没有增加的情况下引起应力的增加,以保证延伸继续如常进行。

During this ductile extension, the material becomes thinner, until a stage is reached when, if the material has not already broken, the thinning becomes localized, and the material eventually breaks. The local thinning is called waisting or necking.

当这种延伸扩大时,材料变得更薄,直至某一阶段达到时,此时材料仍不断裂,只是局部变薄,直至材料最终发生断裂。这种局部变薄现象叫做腰缩或颈缩。

A fact of great importance for geology is that brittle materials such as rocks tend to become ductile when subjected to large hydrostatic pressure

地质水中一个十分主要的事实是:当受到很大水压时,脆性材料如岩石等有变成延性材料的趋势。

Nickel-plated ductile iron--Nickel coatings have received wide acceptance for use in chemical processing. These coatings have very high tensile strength, 50 to 225 ksi.

镀镍球墨铸铁--在化学处理中,镀镍被广泛接受。镍镀层具有很高的抗拉强度,高达50到225ksi(每平方英寸的千磅数)。

For pressure-containing parts, such as valve bodies, ductile iron must meet requirements of aSTM a-395 or a-536.

对于压力容器部分,例如阀体,球墨铸铁必须符合aSTM a-395或a-536的要求。

Stems shall be of dezincification-resistant silicon bronze aSTM B 371 or low-zinc alloy B 99, non-asbestos packing and malleable or ductile iron handwheel.

阀杆材质是符合美国材料试验协会aSTM B371标准抗失锌现象的硅青铜,或B99低锌合金,不含石棉的填料,和可锻或球墨铸铁手轮。

"The valve body material shall be shock resistant ductile iron with extended neck for 2"" of insulation. There will be no exposed fasteners in the waterway to pin the disc to the stem."

阀体材料是抗冲击的球墨铸铁,可在密封状态下将阀颈延长2英寸。在水路里没有暴露的固定件用来把蝶阀固定在阀杆上。

If the carbon content of the steel is below 0.2 percent, the product is mild steel, which is quite ductile .

钢的含碳如低于1.2%就是延展性好的软钢。

Another important property of metals is that many of them are ductile , that is, their shape can be changed permanently by the application of a force without breaking.

金属的另一个重要性能是延展性,即可对金属施加压力使其永久改变形状而不破裂。
