Abstract
This study investigated the microstructure and room temperature mechanical properties of W-7Ni-3Fe (wt%) tungsten heavy alloy (as-fabricated) which was manufactured by metal injection molding (MIM). To identify the effect of heat treatment on the W-7Ni-3Fe alloy, its properties were compared after heattreatment (1,100 oC for 1 hour) in vacuum atmosphere......

DOI:
https://doi.org/10.3365/KJMM.2018.56.2.121
Abstract
This study manufactured Fe-Cr-Ni-based alloy (HK30) using the metal injection molding (MIM) process and investigated the microstructure and room·high temperature mechanical properties of the material. The effect of hot isostatic pressing (HIP) on properties was also examined. The average grain sizes were 24.1 µm for an MIM specimen and 29.1.....
