The role of stress is generally considered or the stress intensity factor in case of precracked samples as an effect with the passage of time in a given system. There is a threshold stress value below which corrosion does not occur even for long test duration. The threshold stress is not just a function of … Continue reading How stress influences Stress corrosion cracking

Inconel 718 is a widely used superalloy that is relatively economical however has good mechanical characteristics. Inconel 718 is heat processed at different temperatures. The grain sizes were measured on both samples by using Light Optical Microscope. The mechanical test results show the damage of tensile strength and hardness while enhancement of creep life with … Continue reading Effect of grain size on mechanical properties of Inconel 718
