Precision Apparatus Using Low Thermal Expansion Component
摘要:
A low temperature history indication plate 31 made of a low thermal expansion material used within an apparatus is provided on the outer surface of the apparatus. A surface of the low temperature history indication plate 31 is mirror polished. Simply by observing the low temperature history indication plate 31, it can be determined whether or not martensitic transformation has occurred.
