Series: ASM Technical Books
Publisher: ASM International
Published: 01 December 2001
DOI: 10.31399/asm.tb.aub.t61170587
EISBN: 978-1-62708-297-6
... Abstract This article discusses the role of alloying in the production and use of low-expansion alloys such as iron-nickel (Invar), iron-nickel-chromium (Elinvar), and iron-nickel-cobalt (Super-Invar and Kovar). It explains how the coefficient of thermal expansion varies with nickel content...

By A. F. Clark
Series: ASM Technical Books
Publisher: ASM International
Published: 01 June 1983
DOI: 10.31399/asm.tb.mlt.t62860075
EISBN: 978-1-62708-348-5
... Abstract Specific heat and thermal expansion are closely related. Following a discussion on thermal expansion theory, methods of measurement techniques are presented along with their advantages and disadvantages. The results of the measurements are then summarized for three classes of materials...
