  on the cooling rate
Dependence of the Fluctuation Free Volume of Amorphous Substances on the Cooling Rate
      
The dependence of the fraction fg of fluctuation free volume (frozen at the glass transition temperature) on the cooling rate is determined using the Bartenev equation for the dependence of the glass transition temperature on the cooling rate.
      
Contrary to the kinetic character of the liquid-glass transition, the glass-transition temperature is a thermodynamic parameter of the amorphous substance, depending parametrically on the cooling rate.
      
In lithium-doped samples the HTSC phase forms at lower temperatures and shorter anneals and it depends on the cooling rate following the anneal.
      
Upon heating of the nanoparticles above the melting point and subsequent gradual cooling, the formation of a cluster structure depends strongly on the cooling rate.

By means of high resolution particle-tracking autoradiography the regularity of boron segregation to austenite grain boundaries has been studied, and the boron concentration profiles across segregated grain boundaries and characteristic parameters for non-equilibrium grain boundary segregation (width of boron-depleted zone, degree and width of boron-segregated band) have been measured. It has been shown that this kind of grain boundary segregation has following features:There exists boron-depleted zone adjacent to segregated grain boundary, which is responsible for supplying of boron to grain boundary during cooling. This kind ofl segregation during cooling is very sensitive to cooling rate. Rapid cooling can inhibit it, and the segregation state would progressively develop from continuous band to discontinuous aggregation and even apparent precipitation as cooling rate decreases. The width of boron-depleted zone is inversely proportional to the square root of cooling rate. The temperature relationship of segregation opposites to the expectation of equilibrium grain boundary segregation. The higher the quenching temperature, the more incremental are the segregated degree and the width of boron depleted zone.The test has been demonstrated that the boron segregation at austenite grain boundaries in quenched steel is a non-equilibrium grain boundary segregation phenomena occurred during cooling.

采用高分辨率的径迹显微照相技术,研究了淬火硼钢中硼向奥氏体晶界偏聚的规律,定量地测定出跨过奥氏体晶界的硼的成分剖面图以及非平衡晶界偏聚的特征参量(晶界贫硼区宽度、晶界富集程度和富集带宽度)。试验表明,这种偏聚具有如下特征: 在偏聚晶界的两侧存在有一定宽度的贫硼区,晶界偏聚的硼是在冷却过程中由该区富集而来;这种偏聚对冷却速度很敏感,急速冷却可以抑制这种偏聚。冷却速度降低,晶界偏聚由连续的偏聚带,逐步发展为不连续的聚集直至明显地析出硼相,贫硼区宽度与冷却速度的平方根成反比;它的温度关系与晶界平衡偏聚预言相反,随淬火温度升高,晶界偏聚程度与贫硼区宽度增加。通过试验,论证了淬火钢中硼向奥氏体晶界的偏聚,是在冷却过程中发生的一种非平衡的晶界偏聚现象。

The effects of the cooling rate and the added elements Ti, B, V, Zr on the dendrite arm spacing and grain size of the Al-5.0Cu-0.8Mn alloy are investigated.The results show that the enhancement of the cooling rate decreases the dendrite arm spacings of the alloy, and at the same cooling rate the addition of the refining elements such as Ti, B, V, Zr narrows the solute-rich band in the solid-liquid interface because the elements restrain the growth of the dendrite. In result, the dendrite arm spacing and grain...

The transitions between the forms of the graphite in the unidirectional solidifiction specimens were observed and analysed by means of the Optical microscopy and scanning electron microscopy(SEM) .The results indicate that the graphite morphology could transform progressively from a nodular one to c/v one and then to a flake one as the retained Rare-Earth element decresing. This process is a continous one and need not renucleat-ing.The result of electron probe (WDS)analysis indicates that there is an enriched zone of Ce in the growth front of c/v graphite. Moreover, the mutual effection between RE concentration and cooling rate on the morphology was analysed.The result indicates that the raising of thecooling rate is similar to the increase of the RE concentration.

本文用金相显微镜和扫描电镜对定向凝固试样中各种石墨形态的转化进行了观察分析。结果表明:随着残留稀土元素含量的下降,石墨形态会出现球墨→蠕墨→片墨的序列转化,并且,这些转变都是一个连续的过程,无需重新形核。电子探针分析结果表明:在蠕虫状石墨的生长前沿有稀土元素Ce的富集。此外,还对冷却速度和稀土元素含量对石墨形态的交互作用进行了分析。结果表明:在不出现白口的条件下,提高冷却速度(即凝固速度)与增加稀土元素含量有相似的效果。
