Linear matching method for design limits in plasticity [PDF]
, 2010 In this paper a state-of-the-art numerical method is discussed for the evaluation of the shakedown and ratchet limits for an elastic-perfectly plastic body subjected to cyclic thermal and mechanical load history. The limit load or collapse load, i.e. the

Fireside corrosion degradation of ferritic alloys at 600°C in oxy-fired conditions [PDF]
, 2014 This paper reports the results of a study carried out to investigate the effects of simulated coal/biomass combustion conditions on the fireside corrosion. The 1000 h deposit recoat exposure (5 × 200 h cycles) was carried out at 600 °C.

Engineering Reports, Volume 6, Issue 9, September 2024.The review is in relation to coating materials that can withstand thermochemical cycle corrosive environments. The overall assessment is that very limited sets of coating‐substrate system are likely to survive for an extended period in the high temperature thermochemical environment. Recommended solution is to use special metals coated with metallic or

Materials and Corrosion, Volume 75, Issue 8, Page 950-964, August 2024.Weld clads of three FeCrAl alloys and reference Alloy 625 were exposed for 6 months in a waste‐fired combined heat and power plant. Microstructure and hardness were investigated before and after the exposure. Metal‐loss rate and corrosion products were analysed, and alloys were ranked from higher to lower erosion–corrosion resistance.
