Adiabatic Shear in annealed and shock - hardened iron and in quenched and tempered 4340 steel
Adiabatic shear localization is a catastrophic failure mechanism which can occur in ductile metals under high strain rate loading. This mechanism is driven by a thermal instability process in which rapid temperature rise due to plastic work couples with thermal softening to cause uniform deformation to collapse into narrow bands of intense shear within which material ductility is exhausted. Adi...
متن کاملThe effect of repeated repair welding on microstructure and mechanical properties of quenched and tempered steel A517
A517 is a low alloy high-strength steels that due to its high strength, toughness and weldability is used in ship building and submarine hulks. The welded areas of this steel often require repairs. In this study, the effect of number of welding repair on microstructure and mechanical properties of A517 steel is studied. Four samples (samples without repair, once repaired, twice repaired, and th...

متن کاملAdiabatic Shear in Remco Iron and Quenched and Tempered 4340 Steel
Adiabatic shear localization is studied in two ferrous metals, Remco Iron, a high purity alpha iron, and 4340 steel, quenched and tempered at 650°C. Punching-shear experiments are performed in a compressive split-Hopkinson bar producing shear strain rates of 45,000 s-'. Optical and scanning electron microscopy was performed on the deformed shear specimens to determine the extent of shear locali...
متن کاملInvestigation of Wear Mechanism in Quenched and Tempered Medium Carbon-High Chromium Martensitic Steel Using Dry Sand/Rubber Wheel
The aim of the present study was to investigate the effect of quenching and tempering temperatures on the microstructure, mechanical properties and the wear characteristics of medium carbon-high chromium wear resistant steel. In addition, the dominant wear mechanisms were studied. For this purpose, austenitizing and tempering temperatures were selected in the ranges of 900- 1000 °C and 300- 500...
