(XAFS) and in-situ Raman spectra revealed that tiny Bi clusters were formed in Bi-MOF-TS, and both Bi-MOF-MF and Bi-MOF-TS underwent a more drastic reconstruction process during CO2RR due to the weaker Bi–O bonding strength. High-angle annular dark-field scanning transmission electron ...

aSS400热轧带钢存在力学性能不合格现象,对力学性能不合格的SS400试样进行化学成分、夹杂物、金相组织分析。结果表明:SS400热轧带钢抗拉强度Rm偏低的主要原因有两个,一是Mn含量偏低;二是厚度较大的热轧带钢轧后冷却时,层流冷却能力不足,卷取温度偏高,导致晶粒粗大,最终造成热轧带钢强度不合格。断后伸长率不合格的原因是...
