The mechanism of V-N microalloying improving the strengthening and toughening of low-alloy structural steel shows that the enhancement in mechanical properties of 16MnV(N) is mainly due to microstructure refining and precipitation strengthening.
对V-N微合金化提高低合金结构钢强韧性的机理进行了研究。
The strengthening and toughening of 20SiMnTi steel whose original structure are martensite,upper bainite.
研究了原始组织为马氏体、贝氏体和正火态组织的 2 0 Si Mn Ti钢经亚温淬火后的强韧性。
The results showed that a (M+F) dual phase microstructure was obtained by intercritical hardening which not only could increase strengthening and toughening of the vice clamp, but also has the property of uniform hardness and lower tendency to the quenching distortion and cracking.
研究表明，经亚温淬火获得（Ｍ＋Ｆ）双相组织不仅能提高零件的强韧性，而且具有硬度均匀和减小淬火变形、开裂的特点。
