High temperature creep in cast Ni-Cr-W-C alloys
Sklenička, Václav ; Kudrman, J. ; Kuchařová, Květa ; Daněk, Rostislav ; Hrbáček, K.
A comparison between the creep characteristics of the two model Ni-Cr-W-C alloys under comparable creep conditions shows that creep strengthening is strongly dependent on the tungsten content.
Properties of NiCrW alloys during long-term high-temperature annealing
Kudrman, J. ; Podhorná, B. ; Hrbáček, K. ; Sklenička, Václav
The results of investigation of mechanical properties and their changes during long-term annealing are presented for model NiCrWC alloys. The relationship between the alloy properties and its microstructure is discussed.
Properties and microstructure of cast nickel-chromium alloys containing tungsten and carbon as alloying elements
Kudrman, J. ; Sklenička, Václav ; Čmakal, J.
Model fast nickel-chromium alloys containing W and C as alloying elements exhibit markedly better creep resistance than is possible with currently available commercial nickel-chromium alloys. The model alloys are reinforced by primary and secondary tungsten carbides.
