This invention relates to a new type nanometer crystal Fe-Zr-Nb-Si-Al-Cu series soft magnetic alloy super thin band and its process technology in which, the mother alloy is smelted by vacuum IF induction oven, an amorphous band is processed by a single quick cooling device to be processed by magnetic field heating at last to get the needed product with good soft magnet performance and iron core made by the super thin band improves its magnetic performance greatly.

本发明为一种新型纳米晶Fe-Zr-Nb-Si-Al-Cu系软磁合金超薄带及其制备工艺。由真空中频感应炉冶炼母合金，用单辊冷急装置制得非晶带，最后对非晶带进行磁场热处理，从而制得所需产品。本发明的合金超薄带具有优良的软磁性能，生产成本也较低。由本发明的超薄带制得的铁芯，其磁性能有很大改善，在国防和民用工业方面有广泛用途。

Both burials, a 45- to 55-year-old female and a 13- to 14-year-old subadult, were buried in a manner similar to "JB" and had the initials "IB-45" and "NB-13" spelled, respectively, in tacks on the coffin lid.

这两具遗骨，一个是45到55岁之间的女性，一个是13到14岁的未成年人。她们都以类似于"JB"的方式被埋葬，一个是"IB －45"，一个是"NB －12"，都用大头钉钉在棺材盖上。

Sliding friction characteristics of these films against U-Nb alloy pin were evaluated by a pin-disc tribometer and Scan Electrical Microscopy.

The protoliths of the chlorite-actinolite schist were mainly volcanic-sedimentary rocks enriched in basalt. The chlorite-actinolite schist and the altered pillowbasalt are characterized by high contents of TiO5, P2O5 and MgO, LREE-enriched patterns with negative Eu anomalies, and "tumescence" patterns for trace elements with enrichment in Nb, Ta and Ti; these are typical characteristics of "OIB-type" alkaline basalt.

绿泥阳起石片岩的原岩主要为富含玄武岩的火山－沉积岩系，绿泥阳起石片岩和蚀变枕状玄武岩具有TiO2、P2O5、MgO含量较高和LREE富集型、无Eu异常，以及"大隆起"微量元素配分模式和富集Nb、Ta、Ti元素等地球化学特征，显示为较典型的洋岛型碱性玄武岩性质。
