In order to study the metadynamic recrystallization behavior of 34CrNi3MoV steel, a double-pass isothermal compression experiment and single-pass thermal interval were designed conducted obtain stress–strain curves under different deformation conditions explore action law parameters during process. The softening rate was calculated by compensation method, grain size in region measured. Based on...

Alloys meeting the requirements of “700 °C and above” advanced ultra-super-critical technology, with higher thermal efficiency, have been developed in recent years. Here, a new wrought Ni-based superalloy excellent high-temperature creep strength based on Waspaloy has is proposed as candidate material for application 700 class steam turbine blades. In this alloy, Molybdenum (Mo) partially repla...

Cast refractory alloys Mo–Nb–Si–B were prepared by centrifugal self-propagating high-temperature synthesis (SHS) from metallothermic mixtures containing MoO3, Nb2O5, Al, Si, and B powders, additive of Al2O3 as a temperature-moderating chemically inert agent. Variation in the acceleration amount affected composition structure cast alloys. In wide range values, combustion temperature was found to...

Elemental powders of iron (Fe), molybdenum (Mo), and carbon (C) were mixed in a pot mill to obtain the compositions C45, C45–1% Mo, C45–2% Mo steels. They then compacted sintered. The sintered preforms had density 75% theoretical (TD). Then, subjected densification two densities 80% 85% TD through forging. densified alloy steel subsequently machined required wear test specimens. experiments con...

The ternary Ti-Mo-N system is an important material that finds applications as a surface coating, hardener, and wear corrosion protective layer. Knowledge of the phase equilibria, transformations, stabilities this alloy for realizing its potential applications. In paper, formation energies three intermetallic compounds, Mo2N-beta, Mo2N-gamma, MoN-delta, were determined from ab-initio calculatio...
