时效

The means of experiments including fresh fracture surface, dislocation morphology adjacent to tensile fracture surface and longitudinal microsection of failed tensile specimen observing, Auger spectrum analysing and in-situ investigating of crack growth.

为深入研究Al—Li合金低塑性沿晶断裂的原因，论文对合金自然时效和峰值时效态的断裂行为进行了较全面的分析，所采用的实验手段包括：拉伸断口纵剖面观察、新鲜断口观察、断面俄歇能谱成分分析，裂纹扩展动态观察及断口附近位错形态观察。

Alloy can obtain the optimistical combination of strength and ductility in T8 temper: Solution-treated at 510℃ for 1h + water ...

2.2197合金在T6状态欠时效以δ′相强化为主，峰时效以少量δ′、θ′和T1相联合强化为主，虽然T1相的强化效果远远优于δ′、θ′相，但由于该合金不是主要以大量T1相强化为主，因而2197合金只具有中等强度。

It can be observed that Guinier-Preston zones are formed on {111} planes to have the platelike structure when sample is aged for 1 h. They grow up gradually with the increasing ageing time.

在时效1h内，Guinier-Preston区即在{111}面上形成并具有片状结构，随着时效时间增加，G-P区逐渐长大。

The prescription leads to the reallotment of the rights, but the traditional prescription doesn't adapt to the improvement of the modern society in which everyone is seaching for the maximum of the use of the social resources.

时效导致了权利的重新配置，而以维护社会秩序为主旨的传统时效在价值取向上已不再适应以追求社会资源利用最大化为目标的现代社会的发展需要，因为权利是社会的稀缺资源，权利配置的最终目的就是要使得权利能最大发挥效用，所以作为权利配置方式之一的时效应以效率为首要价值。

Compared with the corresponding article in the 1979 criminal code, the provision of article 88 is a disadvantage for the defendant. This is also because the crimes before the entry into force of the criminal code shall be subject to prosecution under the provisions of Section 8, Chapter IV of the general provisions of this law. Namely, this provision affirms retroaction of limitations of prosecution. If an act committed by a defendant under provision article 88, that has exceeded the period of limitations of the prosecution, it may inflict criminal responsibility.

刑法第88条的规定与1979年刑法的相关条文相比，一定程度上恶化了被告人的利益，同时，由于刑法第12条对新刑法生效以前实施的犯罪行为"依照本法总则第四章第八节的规定"判断是否应当追诉，肯定了第四章第八节追诉时效的溯及力，如果被告人的行为符合第88条的规定，即使依照旧刑法，已经超过追诉时效的，也可以追究刑事责任。

The stress amplitude and aging time of single serration varies with temperature, strain rate and strain, which tend to be in accordance with the dynamic strain aging theory.

单个锯齿的应力幅度和时效时间随温度、应变速率和应变量的变化基本符合动态应变时效的理论。

Changes of average stress amplitude and aging time of the serrated flow with aging conditions of the samples are assumed to be related to the size of δ′particles and the distance between them, and their changes with deformation are similar to both the type A and B serration.

不同类型锯齿的平均时效时间和应力幅度的变化相似。晶体的位向对锯齿产生的临界应变，锯齿的平均幅度和时效时间都有影响。

In the same solution condition, the surface hardness of T alloy increased with increasing the aging temperatures.

T材合金在同一个固溶处理条件下，表面硬度随著时效温度的升高，到时效温度550℃左右可达最大值。
