The surface is a typical brittle and cleavage fracture
It proposes that unstable cleavage fracture
occurs when the local tensile stress ([[sigma].
Mold life can be reduced due to heat checking (also known as thermal fatigue), cleavage fracture
across die segments, mold erosion due to metal flow, and chemical attack or corrosion.
Investigation of mechanism of cleavage fracture
initiation in intercritically coarse grained heat affected zone of HSLA steel
Mani also recommends that foundries work with the end user to specify the amount of cleavage fracture
acceptable at a specified low temperature for the grade of iron based on the performance criteria of the casting.
