heat of precipitation的意思|示意

These precipitation-hardened aluminum alloys gain their high strengths through heat treatment involving a severe quenching operation, which introduces a very high level of residual stresses.

航空铝合金为了获得高强韧性，必须进行固溶与时效处理，在淬火过程中产生很大的淬火残余应力。

The results show that the distribution of the precipitation of the alloy as-cast is homogeneous if a reasonable heat treatment procedure is chosen.

结果表明：选择合适的热处理工艺，能使铸态合金中的沉淀相均匀析出；

There are better relationships between the spring heat anomalies over the TP to the anomalies of China temperature and precipitation in spring and summer.

春季高原热力异常与我国春夏的气温、降水异常有较好的关系。

Therefere it is considered that in the si crystals adopted and the heat treatment used in the experiment, the homogeneous nucleation may be the leading form of the oxygen precipitation.

因此认为，对所采用的硅单晶在具体工艺条件下，氧沉淀是以均匀成核为主。

The effects of high temperature pre-precipitation on the stress corrosion properties of the heat affected zone were also studied after welding.
