The oxidation behaviour of K-52 austenitic steel with rare earth elements investigated at
1000° C for up to 150 h. The oxidation kinetics indicated that the addition of the rare earth …

The microstructure and phase composition of the heat resistant Fe–Cr–Ni–C alloy of the HP
series (0.45 С–25Cr–35Ni) in the as cast condition and after holding at 1150° C during 2 …

In this investigation, Cr2O3 and MnCr2O4 were comparatively tested at 1050° C in
carbonaceous environment with varied oxygen partial pressures. MnCr2O4 exhibits much …

The structure of niobium carbide particles in as-cast heat resistant modified HP40NbTi alloy
have been studied by light and electron microscopy, electron microprobe and X-ray …

Alloy development plays a vital role in the technological advancement in steam-methane
reformers, with development remaining stagnant in the past three decades. This critical …

Oxidation behavior at the tips of several stress corrosion cracking (SCC) crack, including
intergranular SCC (IGSCC) and transgranular SCC (TGSCC) cracks, in heat-treated 304L …

The failure of ethylene cracking tubes at an elevation of about 5 m in radiant chambers after
one-year service has been analysed. Bulges and circumferential cracks, oriented towards …

The behaviors of the oxidation and carburizing of the HP40Nb furnace tube after 100,000 h
service in high temperature and strong carburizing environment were analyzed in this study …

The effect of rare earth elements on cyclic oxidation behaviour of HP40 at 1373K has been
investigated. The results demonstrate that 0.06 wt.% addition of Y effectively improves the …

The isothermal oxidation behaviors of the Fe-25Cr-20Ni-χNb (0–1.6 wt.%) weld metals have
been investigated in air at 1100° C. Results showed that niobium has a detrimental effect on …
