Abstract
Powder of amorphous Fe-16Cr-8Mo-18C-4Si having a size below 25 mu m has been produced by ultrasonic helium atomization. A fully dense material with finely and homogeneously mixed structure of BETA plus M//7C//3 plus M//6C phases can be obtained by hot pressing at 1300 to 1350 K. The packing fraction is about 100% and the particle size and the interparticle distance of the carbides are 0. 6 - 1. 0 mu m and 1. 2 - 1. 9 mu m, respectively. The alloy has high hardness, e. g. , 965 DPN at room temperature and 400 DPN at 1 073 K as well as good wear resistance which is comparable to the highest value of commercial wear resistant high alloy steel.
