acicular bainite

基本解釋

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(guò)光學(xué)顯微鏡、掃描電鏡、透射電鏡研究表明：最終組織為細(xì)小的針狀鐵素體或準(zhǔn)多邊形鐵素體、珠光體及少量粒狀貝氏體等組成的混合組織。
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.
低碳低合金鋼焊縫金屬的顯微組織基本上包括先共析鐵素體、針狀鐵素體、側(cè)板條鐵素體、少量的粒狀貝氏體和馬氏體。
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(zhǔn)鑄態(tài)貝氏體低碳球鐵韌塑性的提高，與其組織中形成的大量奧氏體和鑲嵌在當(dāng)中的針狀無(wú)碳貝氏體密切相關(guān)。
