大家知道粉末冶金在近20年中所经历的巨大发展,一直忽视了铝这样一种重要的材料。如果浏览许多现有的关于粉末冶金的书籍,便会发现,很少论及到铝或者根本就没有这方面的叙述。因此,使人含混不清,認为铝似乎不宜用于粉末冶金。铝粉的直接使用事实上是有困难的,因而铝只能作为合金元素用于烧结材料,如加入烧结磁铁中。这些困难在于,铝单一的粉末微粒被细 We all know that powder metallurgy has undergone tremendous development in the past 20 years and has always overlooked such an important material as aluminum. If you look at many of the existing books on powder metallurgy, you will find that there is little talk of aluminum or no description at all. As a result, people are confused, think aluminum is not suitable for powder metallurgy. The direct use of aluminum powder is in fact difficult, and therefore aluminum can only be used as an alloying element for sintering materials such as sintered magnets. These difficulties are that aluminum single powder particles are fine
