Failure analysis of hot forging dies for automotive components

Influencing variables and causes of hot forging die failures for automotive components are summarized. Characteristics of hot forging die failures are exemplified. An important role of microfractography is stressed in engineering failure analysis for hot forging die failures. ailure analyzed examples for hot forging die failures and their countermeasures are presented with influencing variables such as die materials, die design, die manufacturing and forging operations. Finally a couple of recommended works for engineering failure analysis for hot forging die failures for automotive components are touched on briefly.
