Jan 01, 2012 · osti.gov journal article:analysis of necking deformation and fracture characteristics of irradiated a533b rpv steel Application of the Materials-by-Design Methodology to Dec 08, 2015 · Since the steels under investigation are often used in high-strain-rate applications, fracture toughness will be characterized by the dynamic stress intensity factor \(K_{\text{Id}}\). A bainite-dominated matrix typically possesses a dynamic fracture toughness of around 150 MPa.m 1/2, and this value will be adopted in the present work.

Oct 04, 2013 · D. Nolan et al., Estimation of Fracture Toughness of Nitride Compound Layers on Tool Steel by Application of the Vickers Indentation Method, Surf. Coat. Technol., 2006, 201(12), p 182188 Article Google Scholar Flux Type and Strength/Fracture Toughness of Mild Steel Pt Tests to examine the influence of the flux on the strength and toughness of two-pass submerged arc welds in 30mm thick mild steel have been made with a range of fluxes. Unalloyed wires were used to give weld Mn contents of approximately 1%. Some additional tests were made to explore the effects of Mn content and also of section thickness. This report examines two-pass welds. Fracture Toughness of Tool Steels:Part One ::Total Stringent selection and processing of tool steels is a critical concern relating to fracture toughness and the application will in most cases determine the material of choice, additions to increase resistance to cracking and the heat treatment process themselves.

Hard inclusions such as Al 2 O 3, SiO 2 and 3Al 2 O 3 ·SiO 2 will fracture during rolling and form hard fragments. This is detrimental for final mechanical properties and for the cutting tools during machining of such steel grades. In addition, Al 2 O 3-based inclusions often cause nozzle clogging during casting. Calcium addition results in inclusion compositions moving in the direction of the arrows, towards Void nucleation in spheroidized steels during tensile Abstract. An investigation was conducted to determine the effects of various mechanical and material parameters on void formation at cementite particles in axisymmetric tensile specimens of spheroidized plain carbon steels.Fracture Toughness of Tool Steels:Part Two ::Total The fracture toughness parameter KIC was obtained from the curve at the point that corresponds to the crack growth a = 2% ao. On the basis of the data presented in work, it may be assumed that the fracture toughness of heat treated AISI D6 tool steel has dropped to 25.9 MPa.m 1/2 compared with 44 MPa.m 1/2 before heat treatment (Figures 3 and 4). Thus, heat treatment increased the yield stress by 40%, but decreased toughness
