Carlan et al JNM 2004, Alloy chemistry of optimized Grade 92 is adjusted to. Reduce Ni Si and Mn contents which tend to impair creep. Reduce Cr23C6 type precipitates and increase MX type. precipitates for better high temperature performance. Computational alloy thermodynamics is used to, visualize the effect of alloy chemistry changes on. phase constituents which provide key information,to alloy microstructure and subsequent. thermomechanical treatment process,Optimized Grade 92.
Thermomechanical Treatment TMT, TMT can be easily implemented during conventional Grade 92 production. TMT significantly introducing additional nucleation sites for MX precipitates and. possible refining grain size would noticeably increase material s performance. Creep Resistance, Creep tests have being conducted at 550 600 and 650C and various loads. The longest test has achieved 12 500 h at 550C, The test results indicate noticeable increases in creep strength as. compared to P92 and P91,200 m 200 m 2 m,Creep cavities lots 2 m and a few up to. 10 m formed close to the rupture site of a,Opt Grade 92 specimen tested at 600C.
