bainitic transformation

It was found that an upper bainitic transformation,γ→α-Fe+γ′-Fe_4N,occurred preferentially at either the grain boundaries or the dislocation lines in the interior of austenite grains,producing a microstructure which,although morphologically looking markedly different,consisted of bainitic packets composed of parallel bainitic ferrite(α-Fe)laths withγ′-Fe_4N lath.

等温转变属于γ→α-Fe+γ′-Fe_4N上贝氏体转变,转变产物由α-Fe板条和γ′-Fe_4N板条交替排列而成的贝氏体板条团以及离散分布在贝氏体团块间的残余奥氏体(γr)小团块组成。

The effect of deformation on bainitic transformation and the microstructure of a microalloyed clean steel and two commercial steels (STE355 and X60) has been studied.

Two stages, meta bainitie and typical bainitie stage, can be observed in the process of bainitic transformation for steels containing alloying elements which can preclude the precipitate of carbides.

含有阻碍碳化物析出的合金元素的钢 ,贝氏体转变过程可以分为二个阶段 :准贝氏体阶段和典型贝氏体阶段 ,准贝氏体阶段组织为贝氏体铁素体和残余奥氏体 ,典型贝氏体阶段组织为贝氏体铁素体和碳化物。

After austenizing at temperature above 820℃, bainite transformation can detected at anstempering at temperature of 350℃.

研究结果表明:试验钢热轧后再经过冷轧形变,其组织为严重变形的饼状铁素体和条带状珠光体,其在奥氏体化过程中相变形核率极高,因而奥氏体化完成后的晶粒度很小,使得随后的冷却转变的组织都比较细小;三种试验钢奥氏体化在350℃、400℃和450℃等温淬火,过冷奥氏体在350℃主要发生贝氏体转变,使钢的强度最大。

The variation of carbon distribution at the grain boundary of austenite during pre bainitic transformation has been investigated by scanning auger microprobe.

运用扫描俄歇微区探针检测贝氏体预转变过程奥氏体晶界附近碳原子的分布，发现碳原子在晶界富集，近晶界区贫碳。
