  • Effect of Segregations on Mechanical Properties and Crack Propagation in Spring Steel
    B. Žužek et alii, Frattura ed Integrità Strutturale, 34 (2015) 160-168; DOI: 10.3221/IGF-ESIS.34.17 Focussed on Crack Paths Effect of segregations on mechanical properties and crack propagation in spring steel B. Žužek, M. Sedlaček, B. Podgornik Institute of Metals and Technology, Lepi pot 11, SI-1000 Ljubljana, Slovenia [email protected] ABSTRACT. Considerable efforts have been made over the last decades to improve performance of spring steels, which would increase the service time of springs and also allow vehicles weight reduction. There are different possibilities of improving properties of spring steels, from modifying the chemical composition of steels to optimizing the deformation process and changing the heat treatment parameters. Another way of improving steel properties is through refining the microstructure and reducing amount of inclusions. Therefore, the focus of the current investigation was to determine the effect of more uniform and cleaner microstructure obtained through electro-slag remelting (ESR) of steel on the mechanical and dynamic properties of spring steel, with special focus on the resistance to fatigue crack propagation. Effect of the microstructure refinement was evaluated in terms of tensile strength, elongation, fracture and impact toughness, and fatigue resistance under bending and tensile loading. After the mechanical tests the fracture surfaces of samples were analyzed using scanning electron microscope (SEM) and the influence of microstructure properties on the crack propagation and crack propagation resistance was studied. Investigation was performed on hot rolled, soft annealed and vacuum heat treated 51CrV4 spring steel produced by conventional continuous casting and compared with steel additional refined through ESR.

  • Influence of Ferrite Content on Fatigue Strength of Quenched and Tempered 42Crmos4 Steel
    Influence of Ferrite Content on Fatigue Strength of Quenched and Tempered 42CrMoS4 Steel Mithaq Elias Hanno Master of Science Thesis Stockholm August 2012 Abstract Specimens of steel 42CrMoS4 were quenched from the austenite (γ) and the ferrite (α) + austenite + cementite phase fields to produce fully martensitic matrices with 0 – 14 % ferrite dispersed in the matrix. After tempering at 300°C or 600°C mechanical and fatigue properties were determined. As expected yield strength, tensile strength and hardness decreased with increased tempering temperature and ferrite content. Quite unexpected, the fatigue properties were mildly affected. A small amount of ferrite, approximately 3% even appears to improve the fatigue strength. Then, at even higher ferrite amounts, slightly below 20% the fatigue strength appears to decrease again.

  • Understanding the Metallurgy in Today's Engines
    New Metals, New Challenges: Understanding The Metallurgy In Today’s Engines By Larry Carley Cast iron is like an old familiar friend to most of our readers because it's been around forever. Vehicle manufacturers like cast iron because it's cheap compared to most other metals, it is strong and durable, and it can be easily cast and machined to make engine blocks, cylinder heads, crankshafts, connecting rods and other engine parts. But as automotive technology continues to move forward, other metals have been replacing ordinary cast iron in many applications. Such "new" metals as high silicon alloy aluminum for engine blocks, aluminum metal matrix composite (MMC), discontinuously reinforced aluminum (DRA), and nickel plated aluminum blocks and cylinders, compacted graphite iron (CGI) engine blocks with or without nickel plated cylinder bores and even bimetal engine blocks made of cast magnesium around aluminum cylinders are finding their way into your shop more often. Powder metal parts that mix iron with other metals are being used in more and more production engines for everything from valve guides and connecting rods to timing gears. In high performance and racing engines, exotic metals such as titanium are now commonly used for valves, springs and retainers. Ceramics, carbon fiber materials or even high temperature plastics may be in tomorrow's engines. Concept engines have been constructed from all of these materials as engineers continue to push the envelope for lighter, stronger and better materials. CAST IRON To better understand some of these new metals, let's start with that metal our readers know well: cast iron.

  • Heredity in the Microstructure and Mechanical Properties of Hot-Rolled Spring Steel Wire 60Si2mna During Heat Treatment Process
    Available online at SciVerse ScienceDirect J. Mater. Sci. Technol., 2013, 29(1), 82e88 Heredity in the Microstructure and Mechanical Properties of Hot-rolled Spring Steel Wire 60Si2MnA during Heat Treatment Process Chaolei Zhang, Leyu Zhou, Yazheng Liu* School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China [Manuscript received February 25, 2012, in revised form May 21, 2012, Available online 27 December 2012] Heredity in the microstructure and mechanical properties of hot-rolled spring steel wire 60Si2MnA during heat treatment process was investigated comprehensively. The steel was isothermally transformed to obtain various hot-rolled microstructure (pearlite fineness within the range of 140e510 nm) and mechanical properties, and followed by some quenchingetempering treatment. Afterwards, microstructure was characterized by optical microscopy, scanning electron microscopy and quantitative metallography, and mechanical properties were determined by tensile test. The results indicated that the hot-rolled microstructure with a coarsen pearlite structure had been changed after reheating, to a austenite microstructure with bigger and more uneven grain size, and finally to a coarsen tempered microstructure. And the average austenite grain size and standard deviation of its distribution in quenched microstructure were observed to depend linearly on the interlamellar spacing in hot-rolled microstructure. Besides, to obtain a good combination of the final strength and plasticity, an optimum value range (190e280 nm) of the interlamellar spacing had been determined for the interlamellar spacing in hot-rolled microstructure. KEY WORDS: Spring steel; Hot-rolling; Heat treatment; Microstructure; Mechanical properties; Heredity 1. Introduction no orientation relationship between the hot-rolled microstructure and mechanical properties of the spring steel was established.

Žarka Dolinara 1, 48000 Koprivnica, Croatia; [email protected] (B.S.); [email protected] (K.H.) * Correspondence: [email protected]; Tel.: +385-51-651-475 Abstract: An increase in technical requirements related to the prediction of mechanical properties of steel engineering components requires a deep understanding of relations which exist between microstructure, chemical composition and mechanical properties. This paper is dedicated to the research of the relation between steel hardness with the microstructure, chemical composition and temperature of isothermal decomposition of austenite. When setting the equations for predicting the hardness of microstructure constituents, it was assumed that: (1) The pearlite hardness depends on the carbon content in a steel and on the undercooling below the critical temperature, (2) the martensite hardness depends primarily on its carbon content, (3) the hardness of bainite can be between that of untempered martensite and pearlite in the same steel. The equations for estimation of microstructure constituents’ hardness after the isothermal decomposition of austenite have been proposed. By the comparison of predicted hardness using a mathematical model with experimental results, it can be concluded that hardness of considered low-alloy steels could be successfully predicted by the proposed model.
