Notes:
The present work is a study on the argon gas pressure effects of Sinter/HIP sintering onmicrostructure and strength of different grades of TiC-NiMo cermets. Titanium carbide in thecomposition of different grades of TiC-NiMo cermets was ranged from 40 to 80 wt.% and the ratioof nickel to molybdenum in the initial powder composition was 1:1, 2:1 and 4:1 respectively. Onthe sintered alloys, the main strength characteristic, transverse rupture strength (TRS) and erosionwear resistance were measured. Furthermore, the microstructure parameters of some alloys weremeasured and the pressure effect on pore elimination was evaluated. All the results were comparedwith common, vacuum sintered alloys. The TRS values of TiC-NiMo cermets could beconsiderably improved by using Sinter/HIP technique, for high-carbide fraction alloys and foralloys sintered at elevated temperatures. The results provide new possible application fields forSinter/HIP-ed TiC cermet materials to areas where, in addition to wear performance, higher strengthproperties are demanded
