时效

Pre-deformation prior to overaging remarkably refine and spheroidize the grain structure of AA2195 Al-Li alloy.

过时效前的轧制预变形明显细化并等轴化AA2195 铝锂合金的晶粒。

It is unreasonable to apply the provision "that Limitation of actions is one year" equally to those subquality products that may be sold after announcement or not.

经过声明可以出售与即使经过声明也不得出售的不合格产品，同一适用&诉讼时效为一年&的规定是不合理的。

通过对均匀化退火后的AZ91镁合金热挤压以及随后的时效处理，分析了形变及时效过程对材料组织与性能的影响。

S the cold worked specimen aged at 400 and 480℃ two peaks were ob- served on the resistivity plot and X-ray relative intensities vs time curve,while two plateaus were found on the thermoelectromotive force curve.

u-Pd-Cr 合金在不同温度退火后室温电阻率增加，在450和850℃达到极大，冷加工时则又减小，硬态试样经400和480℃时效后，电阻率和 X 射线相对强度随时间变化曲线出现两个峰，而在自配热电势曲线上则是两个阶梯。

Article 260 The limitation period for claims with regard to sea towage is one year, counting from the day on which the claimant knew or should have known that his right had been infringed.

第二百六十条有关海上拖航合同的请求权，时效期间为一年，自知道或者应当知道权利被侵害之日起计算。

It i s found that the aged sample suffered more severe corrosion than the unaged samp le.Corrosion type of the aged 310SS is intergrainular,whereas corrosion type of unaged 310SS is uniform.The formation of σ phase due to aging treatment at 700 ℃ for 1000h,reduced Cr content on boundaries in 310SS,which results in the de crease of corrosion resistance of 310SS.

结果表明：经时效处理的310不锈钢比未时效处理者腐蚀严重，前者以晶间腐蚀为主，后者以均匀腐蚀为主。310不锈钢于700℃，100 00 h时效后在晶界大量析出σ相，使晶界附近贫Cr，降低了其抗硫腐蚀性能。

In order to every third party's right can be free from the infringement of the creditor's acclaiming for debt right occurring long time ago. Limitation of action must be designed to cut off the influence on the estimate of property credit, and maintain debt trust system.

为了保障任何第三人不至于因债权人突然行使产生于年代久远而处于休眠状态的权利而受损时效制度切断久远的债权债务关系影响到对当事人财产信用的评价，维护债权信用体系。

Especially, after aging at 750°C for 1000 hours theγ′phase coarsened severely, which lead to the strength and stress rupture life decreased significantly.

GH783合金长期时效后在β相中发现了富Ni的Laves相，但是其对力学性能没有明显影响。

With increasing aging temperature, the precipitates coarsened and tended to segregate at grain boundaries, causing the decreased strength and the degraded SME.

同时添加RE和碳的Fe-25Mn-6Si-5Cr-0.29RE-0.11C合金在不同温度下时效后，获得了含稀土的碳化物沉淀相。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
