什么是低温脆性？低温脆性是指材料的冲击吸收功随温度降低而降低，当试验温度低于tk(韧脆临界转变温度)时，冲击吸收功明显下降，台州pvc管业，材料由韧性状态变为脆性状态，这种现象称为低温脆性。
what is low temperature brittleness? low temperature brittleness means that the impact absorbed energy of material decreases with the decrease of temperature. when the test temperature is lower than tk (critical transition temperature of toughness&brittleness)，pvc管业生产， the impact absorbed energy decreases clears，&the material changes from ductile state to brittle state. this phenomenon is called low temperature brittleness.
