Failure modes of liquid nitrocarburized and heat treated tool steel under monotonic loading conditions
- 92 Downloads
The tensile properties and failure mode of heat treated and liquid nitrocarburized tool steels were studied. The tested steels are used as die and tool materials for plastic molds and punching/blanking dies, where wear resistance is required. In addition to intense friction, the main die block and other die components are subjected to tensile and repetitive stresses during operation (tension and fatigue loading). Therefore, hardness, tensile, and fatigue resistance are also critical quality parameters that contribute to material reliability and tool life. However, this study is an initial component of research and does not include fatigue data.
