Volume: 12
Publisher: ASM International
Published: 01 January 1987
DOI: 10.31399/asm.hb.v12.a0000604
EISBN: 978-1-62708-181-8
... Abstract This article is an atlas of fractographs that helps in understanding the causes and mechanisms of fracture of pearlitic malleable and ferritic malleable white irons, and in identifying and interpreting the morphology of fracture surfaces. The fractographs illustrate the fracture...

EISBN: 978-1-62708-179-5
... Abstract Malleable iron is a type of cast iron that has most of its carbon in the form of irregularly shaped graphite nodules instead of flakes, as in gray iron, or small graphite spherulites, as in ductile iron. This article discusses the production of malleable iron based on the metallurgical...

DOI: 10.31399/asm.hb.v01a.a0006347
EISBN: 978-1-62708-179-5
... Abstract Malleable iron, like ductile iron, possesses considerable ductility and toughness because of its combination of nodular graphite and low-carbon metallic matrix. There are two basic types of malleable iron: blackheart and whiteheart. This article focuses on the blackheart malleable iron...

Published: 01 October 2014
DOI: 10.31399/asm.hb.v04d.a0005969
EISBN: 978-1-62708-168-9
... Abstract This article focuses on heat treatment of malleable and compacted-graphite irons to produce ferritic and pearlitic malleable irons. It describes the heat treatment cycles of malleable iron, including martempering, tempering, bainitic heat treatment, and surface hardening. The article...

EISBN: 978-1-62708-161-0
... Abstract Malleable iron possesses considerable ductility and toughness because of its combination of nodular graphite and a low-carbon metallic matrix. The desired formation of temper carbon in malleable irons has two basic requirements. First, graphite should not form during the solidification...
