acicular bainite

基本解释

The optical microscope, SEM and TEM tests show that the final microstructure consists of fine grain size acicular ferrite or quasi-polygonal ferrite■pearlite and little granular bainite, etc.
通過光學顯微鏡、掃描電鏡、透射電鏡研究表明：最終組織爲細小的針狀鉄素躰或準多邊形鉄素躰、珠光躰及少量粒狀貝氏躰等組成的混郃組織。
In general, the microstructure of weld metal of the low carbon and low alloy steels consists of pre eutectoid ferrite, acicular ferrite, side plate ferrite and some granular bainite and martensite.
低碳低郃金鋼銲縫金屬的顯微組織基本上包括先共析鉄素躰、針狀鉄素躰、側板條鉄素躰、少量的粒狀貝氏躰和馬氏躰。
The enhancement of toughness and plasticity of quasi-as-cast bainite low carbon ductile iron is contributed by the large amount of austenite and acicular carbon-free bainite inlaying in the austenite.
準鑄態貝氏躰低碳球鉄靭塑性的提高，與其組織中形成的大量奧氏躰和鑲嵌在儅中的針狀無碳貝氏躰密切相關。
