Diamalloy 2002 is a special alloysystem containing tungsten carbideand a nickel-based alloy. Such alloysare often used as a powder in specialized coating processes (HVOF:high velocity oxy fuel processes). Tooptimize such processes for aspecific powder, the melting andsolidification range must be known.Presented here are measurementscarried out during heating and cooling. As can be seen, meltingstarts at 966°C and covers a rangeof nearly 300 K. Above 1265°C, thematerial is fully molten. Solidificationoccurred at 1261°C during cooling. Due to the complex nature of suchalloys, the processes of melting andsolidification are quite sophisticatedbut can easily be analyzed byappropriate DSC tests. Bronze is a copper-based alloy usedsince ancient times for the produc- tion of weapons, cans and othermetal products. Nowadays, it isoften used for bearings or springcomponents. Depending on the tincontent and the amount of additives, the melting behavior ofsuch alloys can change. The alloyanalyzed here is generally utilized ininfiltration processes. It shows solid-state phase transitions at 521°C and 568°C (onset temperatures). Meltingstarted at 777°C. The mushy (semi-solid) region covers a range of morethan 200 K. The material is fullymolten above 994°C. Melting of bronze (CuSn) Diamalloy 2002 10
