low temperature martensite的意思|示意

Observations showed that the micro-structure of the steel after forging or high temperature rolling was composed of low-carbon martensite, a little part of bainite and residual austenite.

微观组织观察表明，在锻造或高温轧制状态下获得了以低碳马氏体为主，含少量贝氏体和残余奥氏体的复合组织。

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.

其中针状铁素体之间细小的马氏体的存在与数量对钢的抗拉强度和低温冲击韧性起关键作用。

Reversed austenite, carbide and martensite transformed by the reversed austenite also have significant influence on low-temperature toughness of 9Ni steel.

回转奥氏体、碳化物及回转奥氏体诱发相变生成的马氏体等均对低温韧度产生重要影响。
