Published: 15 January 2021
DOI: 10.31399/asm.hb.v11.a0006777
EISBN: 978-1-62708-295-2
...Abstract Abstract This article briefly reviews the factors that influence the occurrence of intergranular (IG) fractures. Because the appearance of IG fractures is often very similar, the principal focus is placed on the various metallurgical or environmental factors that cause grain boundaries...
