Innovative new materials and microstructures are being continually developed to meet increasingly challenging applications. These newly developed microstructures pose significant challenges in terms of grindability and component distortion. This fundamental study sheds light on the grindability of microstructure variations of through hardened A485–1 grade steel. Results indicate that the phase composition and carbide distribution significantly influence grindability which is characterized in terms of specific grinding energy, G-ratio and part distortion. The study also demonstrates that the numerically quantified carbide distribution exhibits a strong correlation to grindability when phase compositions are similar.

正在不断开发创新的新材料和微结构，以满足越来越具有挑战性的应用。这些新开发的微观结构在可磨性和部件变形方面提出了重大挑战。这项基础研究揭示了淬火 A485-1 级钢微观结构变化的可磨性。结果表明，相组成和碳化物分布显着影响可磨性，其特征在于比磨削能、G 比和零件变形。该研究还表明，当相组成相似时，数值量化的碳化物分布与可磨性有很强的相关性。
