摘要: Abstract Creep crack growth behaviors of the Inconel 625 superalloy at 650 °C are investigated through experimental and numerical methods. The simulated data agree well with results, reflecting that multi-axial creep performance parameter α obtained by present paper can reasonably predict superalloy. initiation time takes up most proportion whole life for all load levels, intergranular fracture is dominated failure mechanism. constraint effect not obvious C∗ to characterize
