Advanced burner-rig test for oxidation-corrosion resistance evaluation of MCrAlY/superalloys systems [PDF]
, 2006 Protective coatings are used on gas turbine components to enable them to survive in engine-operating conditions. This study presents a recently developed cyclic burner-rig test that is used to simulate helicopter engine conditions and to assess the ...

Effects of Hold Time on the Elevated Temperature Fatigue Crack Growth Behavior of Alloy 247LC‐DS
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1794-1808, May 2026.ABSTRACT Creep–fatigue crack growth (CFCG) experiments were performed at 850°C and 950°C on nominally 12.70‐mm‐thick compact‐type specimens of alloy 247LC‐DS, a Ni‐base superalloy. The loading cycles consisted of trapezoidal waveforms with hold times of 2 and 20 min at the maximum force.

Prediction of recrystallisation in single crystal nickel-based superalloys during investment casting
MATEC Web of Conferences, 2014 Production of gas turbines for jet propulsion and power generation requires the manufacture of turbine blades from single crystal nickel-based superalloys, most typically using investment casting.

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 5, Page 1742-1755, May 2026.ABSTRACT In the present study, creep tests of a TiAl alloy were conducted using miniature specimens (d = 2 mm) under various conditions to investigate their creep properties at 760°C. The test results indicate that creep rupture time obtained using miniature specimens at identical applied stress levels increase with the order of test condition Ar gas ...
