Experimental research on Cr-Al mixed powders by mechanical alloying

The changes of microstructure, phase structure and microhardness of Cr-Al mixed powders in the process of mechanical alloying (MA) have been investigated by x-ray diffraction analysis, SEM examination and microstructure testing. The results show that the microstructure of Cr-Al mixed powders subject...

Zusammenfassung:The changes of microstructure, phase structure and microhardness of Cr-Al mixed powders in the process of mechanical alloying (MA) have been investigated by x-ray diffraction analysis, SEM examination and microstructure testing. The results show that the microstructure of Cr-Al mixed powders subjected to mechanical alloying for 96 h exhibits super-saturated solid solution of Cr and intermetallic compound eta -AlCr sub 2 .
