【摘要】 介绍了用激光热导仪对等静压铍材的热导率、比热进行测试的方法及测试结果。得出结论 :等静压铍材比热Cp 在 ( 2 0～ 60 0℃ )区间内随温度t升高而呈直线增加 ;等静压铍材的热导率λ在 ( 2 0～ 60 0℃ )区间内随温度t升高而减小 ,3 0 0℃以前减小速度较大 ,3 0 0℃以后减小速度变缓更多还原

【Abstract】 The testing method and effects of C p (the specific heat content) and λ (the thermal conductivity) of isostatic pressed beryllium material by using laser thermal conducting instrument were introduced.The conclusions are as follows:The C p of isostatic pressed beryllium material linely increases with the increasing of temperature from 20 to 600 ℃. The λ of isostatic pressed beryllium material decreases with increasing of temperature from 20 to 600 ℃. The speed of decreasing of λ is higher before 300 ℃ than after 300 ℃.更多还原
