Studies the effect of the pre-polygonization heat-treatment on the recovery and recrystallization of cold-deformed steel 45 by TEM, tensile test, hardness test and thermal analysis.
Ultrasonic Thickness Gauge, hardness tester, infrared thermometer, and torque wrench and many finished product test equipment etc. Those attribute to conformance rate of delivered products is 100%.
This research for the topic is to do the design and development of the system software and hardware, and to develop a real-time hardness test device for inner wall pump pipe that can be used on site.
hardness testing methods for rubber, vulcanized or thermoplastic
The flexural strength and hardness of the specimens were tested with an instron testing machine and a microhardness tester.
The hardness tester is also equipped with photographic device which may take photo for all measured indentation and the metallographic formation of materials.
