Same Strength, Different Cut

Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode! Episode 164 of the Professor Alex Volinsky podcast. Flake, compacted, and spheroidal graphite irons at nearly equal tensile strength still needed measurably different cutting forces: graphite shape forces different pearlite designs to reach equal strength, and the hardness differences drive tool load. Harder irons cut harder, but not proportionally — strength alone can't predict machinability. Based on the paper: Effect of Microstructure and Mechanical Properties on Cutting Force of Different Cast Irons with Similar Tensile Strength; J. Ren, Z. Li, Y. Xiong, F.-J. Li, F. Ren, A.A. Volinsky; China Foundry, 2019, Vol. 16, pp. 177–183. Hosts Elena and Marcus. AI-generated voices.
