Abstract
A heating and cooling apparatus capable of cyclic heating and cooling of a test specimen undergoing fatigue testing. Cryogenic fluid is passed through a block 10 clamped to the specimen 11 to cool the block and the specimen. Heating cartridges 13 penetrate the block 10 to heat the block and the specimen 11 to very hot temperatures. Control apparatus 36 and 46 is provided to alternately activate the cooling and heating modes to effect cyclic heating and cooling between very hot and very cold temperatures. The block 10 is constructed of minimal mass to facilitate the rapid temperature change thereof.
