LRJ-50 microcomputer-controlled mechanical creep and durability testing machine (hereinafter referred to as the testing machine) is mainly used for the detection of mechanical properties of superalloys, titanium alloys, other ferrous metals and non-ferrous metals. The steady state creep rate, creep limit, creep elongation, lasting breaking time, lasting strength limit, elongation after lasting breaking, section shrinkage and lasting notch sensitivity coefficient were measured.
