The hot tensile test has been used for a variety of steels, to investigate the influence of such factors as inclusions, precipitation, phase transformation and grain size on hot ductility. Tests were performed in the temperature range 700-1000 °C and at a strain .4 _2 1 rates of (10 —10 S ), generally to simulate the conditions experienced during the ...

The role of ductility in hot working [PDF]
, 1967 Strength and ductility are the important characteristics which govern the hot working properties of a material. This paper describes test methods for measuring hot workability and then discusses deformation and fracture mechanisms in hot working. Particular emphasis is laid on the correlation of strength and ductility data in simple materials in terms ...

The hot ductility of steels [PDF]
Hot tensile tests have been performed on a variety of plain carbon and micro-alloyed steels, in order to determine the influence of such factors as phase transformation, grain size and precipitation on hot ductility. The γ-∝ phase transformation has been shown to produce a significant ductility trough in the high temperature tensile behaviour of plain ...

Hot ductility of TWIP steels [PDF]
TWIP (Twining Induced Plasticity) steel is very promising AHSS (Advanced High Strength Steel) grade owing to its superior toughness and ductility. Recently it has attracted the interest of the automotive and steelmaking industries, as the need for reducing weight to provide better fuel efficiency is of paramount importance with the gradual depletion of
