CREEP RUPTURE LIFE OF PRE-STRAINED SUPERALLOY N07080
International Journal of Advanced Research, 2021 The creep of the pre-strained superalloy N07080 is described in this work. The pre-strain was achieved by warm rolling at 1050 oC.-The warm rolling was performed due to additional strengthening, i.e increasing of the superalloy hardness.-The pre-strain drastically reduces the creep rupture life of the superalloy compared to the creep rupture life of ...

Creep Rupture Life Prediction of High Temperature HRSG Tubes [PDF]
Journal of the Korean Society of Safety, 2013 Abstract : The Heat Recovery Steam Generator(HRSG) is a device recycling the exhaust gas of gas turbine in combined power and chemical plants. Since service temperatures was very high, the damage of HRSG tubes intensively occurred in superheater and reheater.
