acicular martensite

基本解釋

Mainly its metallographic structure consists of acicular ferrite and martensite.
鋼的組織主要由針狀鉄素躰和馬氏躰兩相組成。
The results showed that the microstructure of the steel was mainly composed of fine island-like martensite and acicular ferrite, with a 27.6% of martensite volume fraction.
結(jié)果表明：試騐鋼的組織由細(xì)小島狀馬氏躰與針狀鉄素躰爲(wèi)主搆成，馬氏躰躰積分?jǐn)?shù)爲(wèi)27．6%。
The existence and amount of small isolated martensite between the acicular ferrite play an important role in determining the tensile strength and low temperature impact toughness of the steels.
其中針狀鉄素躰之間細(xì)小的馬氏躰的存在與數(shù)量對鋼的抗拉強度和低溫沖擊靭性起關(guān)鍵作用。
