Precisely cast ductile iron gear has advantages of low noise, high abrasion resistance index and long service life.(精密铸造球铁齿轮,噪音低,耐磨度高,使用寿命长。)
And reinforced high-strength lightweight concrete beam is less ductile as compared with the normal-weight concrete beam of the same concrete strength.(纯弯段无腹筋的高强轻集料钢筋混凝土梁在破坏时表现出较强的脆性,延性要比同一强度等级普通混凝土梁略差。)
The descending rock is substantially cooler than the surrounding mantle and hence is less ductile and much more liable to fracture.(下降的岩石比周围的地幔的温度低很多,因此延展性较小,更容易断裂。)
However, in case of ductile materials they cause poor surface finish and low tool life.(可是在塑性材料加工时,造成表面光洁度和刀具寿命低。)
In these cases, the cracks can propagate to the critical length and result in ductile fracture of the component.(出现这种情况后,裂纹的长度会扩展,造成部件延展断裂。)
When the crystal size is about three nanometers (billionths of a meter), the material has its ultra-strong and ductile characteristics.(当晶体大小大约为3纳米(1纳米等于10亿分之一米)时,天然丝材料具有超强的强度与延展性特征。)
The isothermal quenching process of the ductile iron camshaft was analyzed.(对球铁凸轮轴的等温淬火工艺进行了分析。)
So it is necessary to determine the laser absorptivity of ductile iron.(因此,确定球墨铸铁材料对激光的吸收率十分必要。)
Isothermally quenched ductile iron (austempered ductile iron, ADI) is a relatively new material to engineering industries.(等温淬火球铁(adi)对工程界来说是一种相对较新的材料。)
Till the bridge you will need be formed, till the ductile anchor hold.(直到架起你需要的桥,直到下定你韧性的锚。)
