1·Room temperature impact ductility decreased with the aging time increasing.

室温冲击韧度随时效时间的延长整体下降，为韧性断裂；

2·After annealing coarse grain structure was observed and the impact ductility and the elongation of materials increased.

退火以后，发现材料的晶粒长大，材料的冲击韧性与延性提高。

3·The results show that, with the decrease of finishing temperature, the low-temperature impact ductility decreases gradually.

结果表明：随着终轧温度的降低，角钢的冲击韧度逐渐降低；

4·Use these technical parameters, carry the semisolid extrusion shaping to the slurry, then test the impact ductility, rigidity and impacting grinding abrasion.

采用上述工艺参数对浆料进行半固态挤压成形，并对挤压件进行冲击韧性、硬度和冲击磨料磨损测试。

5·The use of polypropylene fiber in concrete of the bridge deck paving can improve its tensile strength, bending strength, permeability strength, impact ductility, cracking resistance and toughness.

在桥面铺装层混凝土中掺用聚丙烯纤维能够增强其抗拉、抗折、抗渗、抗冲击能力，并起到阻裂增韧的作用。

6·The effective method to improve the impact ductility of this zone is to change the welding process and conduct post-weld heat treatment, which is help to divide M-A component into ferrite and carbide.

改善焊接工艺或进行焊后热处理，使M - A组元分解成铁素体和碳化物是提高其韧性的有效方法。

7·The main factors to impact the ductility of SRHSHPC frame columns is theoretically analyzed, and is compared with their experimental results.

同时又结合试验提出了延性与其影响因素的关系式，以期为以后的延性抗震设计提供理论依据。

8·A part surface can be infiltrated with a low melting point metal to increase density, strength, hardness, ductility and impact resistance.

零件表面能被低熔点金属渗透以增大密度、强度、硬度、延展性和抗冲击能力。

9·The treatment improves the tensile strength and ductility of the alloy without reduction of its impact toughness, chiefly because a large amount of substructure remains in it after the heat treatment.

它主要是由于热处理之后大量保留了稳定的亚组织，提高了材料的强度、塑性指标，而不降低材料的冲击韧性。

10·On mechanical properties, the strength was raised obviously, fatigue property was unchanged, impact toughness and ductility were reduced.

在性能方面，强度被显著地提高，机械疲劳性能变化不明显，冲击韧性和塑性降低。
