简易式钢结硬质合金热疲劳试验装置

利用本校热处理实验室现有的设备，自制了一台小型简易式热疲劳试验装置，对碳化钨钢结硬质合金进行了热疲劳试验，该装置结构简单，成本低，使用方便，省时、省水，实用可靠，很易自制。

SIMPLE THERMAL FATIGUE TESTING APPARATUS OF STEEL BONDED CARBIDE

We used the equipment of heat treatmnt test room of our university to have made a simple thermal fatigUe testiug apparatus and made thermal fatigue experimeuts on stee bonded carbide with it. The practice in a few of years has shown that the equipment structure is simple,the cost is low,the using is comvenient,and the apparatus saves times and water,is utility and relisble,and making it by self is very sbople.
