摘要： A method and apparatus is described for enabling the testing and evaluation of industrial machine components and, in particular, gas turbine engine components, under simulated in-situ thermal operating conditions for effectively evaluating new component designs and repair techniques. A specimen machine component/part is placed in a test chamber and cyclically heated and cooled while being monitored to obtain information regarding the initiation and propagation of a crack within the structure of the component. Information regarding the number of heating and cooling cycles sustained by the component until crack initiation and information indicating the rate of crack propagation are acquired and compared over multiple heating-cooling cycles to evaluate components and repair techniques. In one example implementation, the component is monitored during cyclic heating-cooling for spontaneous acoustic emissions and acoustic emission waveform data is recorded and analyzed to determine crack initiation and/or propagation.
