Special Issue Information

Dear Colleagues,

We are pleased to announce this Special Issue of Metals entitled “Mechanical and Structural Properties of Cast Irons”. The cast irons are a wide family of materials that have been applied to all aspects of human development since ancient times. In this light, we invite you to submit valuable contributions that provide a more comprehensive and critical understanding of the state-of-the-art of cast irons and their mechanical and microstructural properties in various conditions and applications.

This Special Issue will consider full papers, communications, and review articles concerning the latest advancements and emerging trends in cast irons, with a special focus on technological innovation.

Submissions (including case studies, experimental and/or analytical approaches) that explore recent developments in improving microstructural, mechanical, wear, and corrosive properties, as well as performance in different extreme conditions, are encouraged.

Dr. Dragan M. Rajnović

This study investigates the influence of quenching and partitioning (Q&P) on the microstructure, hardness, wear resistance, and impact toughness of GG25 gray cast iron, in comparison with as-cast, quenched, quenched-and-tempered, and austempered conditions.

This study investigates the influence of quenching and partitioning (Q&P) on the microstructure, hardness, wear resistance, and impact toughness of GG25 gray cast iron, in comparison with as-cast, quenched, quenched-and-tempered, and austempered conditions. Q&P treatment promotes a significant fraction of retained austenite, with carbon enrichment stabilizing the austenite at room temperature. Microstructural analysis reveals a multiphase matrix composed of partitioned martensite, bainitic ferrite and carbon-enriched retained austenite, while the morphology and distribution of graphite flakes remain unchanged. Mechanical testing shows that Q&P enhances impact toughness without substantial loss of hardness, achieving a balance not observed in conventional quenching and tempering treatments. Tribological evaluation indicates that wear resistance is slightly lower than quenched and tempered samples but superior to as-cast iron, with deformation of retained austenite and tribofilm formation influencing wear behavior. These results demonstrate that Q&P represents a promising route for developing gray cast irons with enhanced toughness and maintained hardness, suitable for components subjected to impact and wear loading.
