Nb-Mo微合金高强钢强化机理及其纳米级碳化物析出行为张正延1,2,孙新军1,雍岐龙1,2,李昭东1,王振强3,王国栋21. 钢铁研究总院工程用钢研究所2. 东北大学轧制技术及连轧自动化国家重点实验室3. 哈尔滨工程大学材料与化学工程学院摘 要:采用SEM,EBSD,HRTEM和物理化学相分析等技术分别对0.1%Nb和0.1%Nb-0.19%Mo微合金低碳热轧钢进行了微观组织形貌,钢中析出相及强化机理的观测和分析.结果表明,与Nb钢相比,Nb-Mo钢的组织较为细小,组织中小角度晶界密度也较高,且Mo的添加使得Nb的析出率升高,尺寸在10 nm以下的纳米级MC型析出相(Nb,Mo)C含量较高,这种纳米级析出相(Nb,Mo)C具有较低的熟化速率,不易粗化,因此具有较高的沉淀强化增量,这也是Nb-Mo钢强度......
binary system were obtained finally. The much better agreement is achieved between the calculated results and the reported experimental data. Key words: Mg-based alloys; phase diagram; thermodynamic... are indispensable to design novel Mg-based alloys. The thermodynamic descriptions of many Mg-based systems have been well established, but there is no perfect one for the Mg-Ga system. Therefore, the purpose......
properties of liquid alloys, liquidus projection and several vertical and isothermal sections of this ternary system were calculated, which are in reasonable agreement with the reported experimental data. Key... of the eutectic reaction in this binary system were measured in Refs.[14-18], as listed in Table 1. Enthalpies of mixing of the Ag-Si liquid alloys have been measured by HASSAM et al[19] at 1 423 K......
cheaper than other BMGs, but also due to the unique combination of high physical, chemical and mechanical properties[4-5]. Since INOUE et al[6] synthesized Fe-Co-(Zr, Nb, Ta)-(Mo, W)-B amorphous alloys...
