退火

simulated annealing algorithm is a random search algorithm, and it can be applied to many problems with little premise information, gradual convergence in the global optimal solution.

模拟退火算法是一种随机搜索算法，可应用于许多前提信息很少的问题，能渐进地收敛于全局最优解。

Probably it can be separated into two kinds. one is qualitative, the other is quantitative. the methods used broad are: layered analytical arithmetic, blurry clustering arithmetic, centrobaric arithmetic, intersectant median arithmetic, ratable arithmetic, p-median arithmetic, meshwork bestrow arithmetic, systemic simnlate arithmetic, genetic arithmetic, blurry qualitfunction arithmetic, minimum route arithmetic, two-double simulate anneal arithmetic.

关于物流中心的选址有很多方法，大致可分为定性和定量两大类，目前使用较多的选址方法有层次分析法、模糊聚类法、重心法、交叉中值法、加权评分法、p－中值法、网络覆盖模型、系统模拟法、遗传算法、模糊品质机能法、最短路径法、双层模拟退火算法等。

The films also can be annealed in air or reductive circumstance according to the requirement.

根据性能的要求也可以选择在空气中或者在还原气氛中退火。

The results show that dynamic softening is easy to occur in these ingots and flow stress becomes steady finally; the material constants of hot deformation are procedural parameters that stress-level coefficient α, strain rate sensibility exponent m and deformation activation energy Q are all increased with strain increasing, while stress exponent n is decreased gradually; the values α and m of the alloy homogenized are the biggest and the value n is the smallest, dynamic softening effect of the alloy is the most obvious, which can deform evenly; influence of strain on the value Q of the alloy homogenized is a little and the average value of Q is only 176.5kJ/mol, so the alloy is easy to deform; the alloy matrix shows the regular recrystallization grains when the strain is 50%; dislocation cell structure re-formed in the grains with increase of strain.

结果表明：经不同处理的Al-1Mn-1Mg合金均易发生动态软化并最终呈现稳态流变特征；热变形材料常数是过程量，随应变量的增加，应力水平参数α、应变速率敏感性指数m和热变形激活能 Q 随之增大，而应力指数 n 则逐渐减小；均匀化退火后，铝合金的α和m值最大而n值最小，动态软化效果最明显且变形均匀，在该状态下，铝合金的 Q 值受变形量影响小，平均仅为176.5kJ/mol，易进行热变形；当应变量为0.7时，基体呈现规则的再结晶晶粒组织，随着应变量的增加，晶内重新形成了位错胞结构。
