The influence of 0.15 or 0.70wt% Ce addition on the oxidation of Fe-15Cr and Fe-30Cr alloys in air at the temperature range between 800 and 1300℃ up to 500hr was studied.The oxidation kinetics indicated that the oxidation rates of Fe-15Cr alloy at 1000℃ and 1100℃ and that of Fe-30Cr alloy at the tem peratures from 1000 to 1200℃ reduced remarkablely owing to the 0.7wt%Ce added.However,the effect of 0.15wt%Ce was much less.

The influence of 0.15 or 0.70wt% Ce addition on the oxidation of Fe-15Cr and Fe-30Cr alloys in air at the temperature range between 800 and 1300℃ up to 500hr was studied.The oxidation kinetics indicated that the oxidation rates of Fe-15Cr alloy at 1000℃ and 1100℃ and that of Fe-30Cr alloy at the tem peratures from 1000 to 1200℃ reduced remarkablely owing to the 0.7wt%Ce added.However,the effect of 0.15wt%Ce was much less. The morphology observation,X-ray diffraction analyses and EPMA were carried out for the oxide layers on test alloys.The studies showed that Cr_2O_3 films could be formed rapidly on the surfaces of all test alloys at an early stage of oxidation,and then the Fe-ion concentration in Cr_2O_3 remained somewhere about 1wt% for a long time.However,the 0.7wt%Ce addition decreased the growth rate of Cr_2O_3 layer slightly.The most obvious effect of Ce was to inhibit Cr_2O_3 layer degeneracy in which Cr_2O_3 was replaced gra- dually by rapidly growing Fe-rich oxide,and to delay the breakaway of oxide film. The concentration of oxygen diffused into alloy from Cr_2O_3 layer is reduced by a factor of 10~7 owing to internal oxidation of Ce.With the reduction of oxygen concentration in alloy,internal oxidation of Si in Fe-15Cr alloys which contained about 0.2wt%Si took place in the vicinity of the Cr_2O_3 layer/alloy interface,so that a SiO_2 interface layer was formed in the Fe-15Cr-0.7Ce alloy.

Fe-15Cr 和 Fe-30Cr 合金在1000至1200℃空气中氧化时,表面富铁氧化伤的发展导致保护性Cr_2O_3层衰退,氧化速率增大。添加 Ce 可延迟衰退过程的发生,从而大幅度减低氧化速率。随氧化温度和合金成份变化,Cr_2O_3层衰退的开始时间和发展特征随之改变,Ce 对氧化行为的影响因而呈现出规律性的变化。研究发现,合金中 Cr 的内氧化使 Cr_2O_3层形成小舌包卷合金并使其氧化成富铁氧化物。这是Cr_2O_3层衰退的原因之一。含 Ce 合金中 Ce 的优先内氧化则降低自氧化层进入合金的氧浓度,抑制Cr 的内氧化。氧浓度降低还能促进 Si 的内氧化物在氧化层/合金界面集聚。

High carbon vanadium alloyed high speed steel/structural steel series bimetal composite was prepared through liquid solid bonding by cast in insertion. The microstructure and morphology of interface of bimetal composite were studied under different bonding conditions. The results show that interface bonding is dependent on superheated outer layer alloys in cast in insertion. It is possible to obtain interface bonding in volume ratio of outer/core materials greater than 8.0, and the bonding mechanism is diffusion bonding. The interface structure of composite consists of core material diffusion layer, chilling solidified layer, directional growth layer, and cellular granular layer. The apparent directional growth is found during solidification process of outer material.The advanced velocity of liquidus solidus has obviously effect on solidification structure of outer material. With 1.25 volume ratio of outer/core material, the fastest solidification velocity of outer material exhibits the rod like pseudo eutectic microstructure in composite. HSS solidification microstructure changes into prolonged cellular grain along the radial heat transfer direction with the increase of volume ration.
