这篇文章评述了人们不大注意的铁基粉末冶金零件整体淬火时，孔隙度与合金含量对其淬透性的影响。
Here an overview of the influence of porosity and alloy content on the Jaminy hardenability of ferrous PM parts is presented.
此结果在使用流动性较差的粉末，轧制孔隙度高和较薄的带材时，获得了良好的应用。
This result has been applied successfully to roll thinner and high porosity strip when the powder has poor fluidity.
因此，必须采用烧结性良好的UO_2粉末和合适的成型烧结条件以使开口孔隙度和细孔隙度降至最低。
So that, it is necessary to adopt very sinterable UO2 powder and suitable pelleting and sintering conditions to minimize open porosity and small porosity.
