摘要： Bulk shapes and solid structures of amorphous metals formed of micron sized particles produced by droplet emulsion technique whereby undercooled droplets are solidified in the amorphous state with a stabilizing coating on the surfaces thereof, the shapes and solid structures being formed by dispersing the stabilizing coating and bringing the particles into intimate metal to metal contact for atomic bonding, without raising the temperature to crystallization temperature.

摘要： An additive for increasing the toughness of thin-wall iron castings is provided. The additive includes amounts of a non-ferrous metal oxide and a metal sulfide in which the non-ferrous metal has an affinity for oxygen less than that of iron, and the metal has an affinity for sulfur less than that of magnesium. The metals contained in the oxides and sulfides are also not alkali, alkali earth or rare earth metals to reduce the incidence of defect formation in the castings. The metal oxide and metal sulfide, when added to a cast iron melt react with magnesium added to the melt as a spheroidizing graphite element to form nucleation sites having a core of magnesium oxide surrounded by magnesium sulfide. These nucleation sites allow for increased nucleation of graphite, whether in vermicular or spheroidal form, such that the cross-section of the thin-wall iron casting is more uniform, thereby decreasing the amount of carbide formed in the casting and increasing the toughness of the casting.
摘要翻译：提供了一种增加薄壁铁铸件韧性的添加剂。添加剂包括有色金属氧化物和金属硫化物的量，其中有色金属对氧的氧亲合性小于铁的亲和力，并且金属对硫的亲和力小于镁的亲和力。包含在氧化物和硫化物中的金属也不是碱金属，碱土金属或稀土金属，以减少铸件中缺陷形成的发生。当加入到铸铁熔体中时，金属氧化物和金属硫化物与添加到熔体中的镁作为球化石墨元件反应以形成具有由硫化镁包围的氧化镁芯的成核位点。这些成核位置允许石墨的成核增加，无论是以蠕虫形状还是球形，使得薄壁铁铸件的横截面更均匀，从而减少铸造中形成的碳化物的量并增加其中的韧性铸件。
