Background technology
Material stands the ability that temperature sharply changes and do not destroy and is called heat-shock resistance (ThermalShockResistance), also known as thermal-shock resistance or thermostability.
Heat-shock resistance is a key property of ceramic (as: pottery, glass, refractory materials etc.). When material be heated suddenly (or catching a cold) expand (or shrink) time, owing to the distortion of its each several part is restricted mutually and produce thermal stresses. When this kind of thermal stresses exceedes the ultimate strength of material, will produce to burst apart, peel off, rupture and destroy. The resistance to heat shocks of material, except affecting by heat transfer conditions, depends primarily on its thermal expansivity, thermal conductivity, fracture toughness property, specific heat, intensity etc., simultaneously also relevant with its weave construction, shape and size etc. In order to prevent material in use, destroy because of thermal shocking, it is desired to material has good resistance to heat shocks, therefore in the research process of material, often need its resistance to heat shocks to be tested.
The representation of thermal shock resistance and testing method have a variety of. The heat-shock resistance of material is generally measured with anxious cold pattern. Conventional expression and test mode have following several:
1., after material rises to different temperature, quench cold (air-cooled or water-cooled), records the maximum temperature difference that specimen surface produces cracking. This heat-shock resistance namely represented with the temperature difference.
2., after material rises to preset temperature, quench cold (air-cooled or water-cooled), after completing stipulated number, before the remaining bending strength of sample and normal temperature thermal shock, the ratio of bending strength, records strength retention. This heat-shock resistance namely weighed with strength retrogression.
3., after material rises to preset temperature, quench cold (air-cooled or water-cooled), test is until material produces the number of times of macrocrack repeatedly. This heat-shock resistance namely weighed with rapid heat cycle cycle index.
At present, for specialize heat-shock resistance experiment equipment rare. Traditional way is: be placed on by sample in conventional high-temperature stove, after being heated to the temperature that experiment needs, manually opens fire door, and taking out one piece one piece, sample from burner hearth, puts into coolant medium container.
