Effect of microstructure and mechanical properties on cutting force of different cast irons with similar tensile strength
Flake graphite iron, compacted graphite iron and spheroidal graphite iron with various tensile strengths were cast. They were selected and grouped according to roughly the same tensile strength, and then the main cutting force in each group was measured and compared. The microstructures of differe...

| description | Flake graphite iron, compacted graphite iron and spheroidal graphite iron with various tensile
strengths were cast. They were selected and grouped according to roughly the same tensile strength, and then
the main cutting force in each group was measured and compared. The microstructures of different cast irons
were characterized. The relationship between the cutting force and microstructure was established. Results
show that the graphite morphology in cast irons determines the strength. In order to obtain the same strength
of the cast iron with sharply edged graphite, more or finer pearlite in the matrix is needed. Graphitic cast irons
with high pearlite content and smaller pearlite interlamellar spacing have higher hardness. For the cast irons with
different graphite morphologies, but almost the same tensile strength, the main cutting force is obviously different,
along with the hardness. Harder cast irons have a greater cutting force, but the difference in cutting force is not
proportional to hardness. |
