Series: ASM Handbook
Volume: 13B
Publisher: ASM International
Published: 01 January 2005
DOI: 10.31399/asm.hb.v13b.a0003825
EISBN: 978-1-62708-183-2
... Abstract Tantalum is one of the most versatile corrosion-resistant metals known. The outstanding corrosion resistance and inertness of tantalum are attributed to a very thin, impervious, protective oxide film that forms on exposure of the metal to slightly anodic or oxidizing conditions...

Published: 27 April 2016
DOI: 10.31399/asm.hb.v03.a0006209
EISBN: 978-1-62708-163-4
... Abstract This article is a compilation of binary alloy phase diagrams for which tantalum (Ta) is the first named element in the binary pair. The diagrams are presented with element compositions in weight percent. The atomic percent compositions are given in a secondary scale. For each binary...

Published: 01 June 2012
DOI: 10.31399/asm.hb.v23.a0005684
EISBN: 978-1-62708-198-6
... Abstract Physically, tantalum is a dark, blue-gray, lusterless metal that exists in two crystalline forms: an alpha-phase with a body-centered cubic structure, and a brittle beta-phase with a tetragonal orientation. This article tabulates the physical and material properties of tantalum...
