Reactive processing and mechanical properties of ZrO2/NiAl intermetallic matrix composite

Ryu, HC Hong, Soon-Hyung Shim, MK

10 volume% ZrO2 reinforced NiAl matrix composite(ZrO2/NiAl) was prepared by reactive hot-pressing of elemental powders. Mixtures of Ni and Al powders with reinforcing particles of partially stabilized ZrO2 have been ball-milled and hot pressed at 980 degrees C under 30 MPa. The hot-pressed billets were extruded at 1200 degrees C with an extrusion r...

Microstructural study of the surface layers irradiated by high-energy electron beam in a plain carbon steel

Suh, DW Lee, SH Koo, YM

An investigation was conducted into the microstructural analyses of the surface layer hardened by the irradiation of high-energy electron bean in a 0.38% C plain carbon steel. Steel specimens were irradiated using an 1.4 MeV electron accelerator, and the microstructures of the irradiated surface layers were examined. The ferrite-pearlite structure ...
