Ausforming of medium carbon steel
Materials Science and Technology, 2015The prospect of enhancing the hardness of low alloy steel for the manufacture of fasteners is examined using ausforming, in which the austenite is deformed rapidly at a low temperature to increase its dislocation density before quenching in order to obtain the harder martensite.

Influence of flow stress of ausformed austenite on strength of ausformed martensite
Materials Chemistry and Physics, 1986Abstract The relationship between the flow stress of austenite at ausforming temperature and the hardness of the ausformed martensite (or austenite) at room temperature was studied using martensitic steel 18CrNiW and austenitic steel 18-8. Ausforming was performed with a torsion test machine at various temperatures between 723K and 923K and at strain

Effect of ausforming on nanobainite steel
Scripta Materialia, 2010The effect of ausforming on kinetics, morphology and crystallography of nanobainite steel was examined by electron backscattered diffraction and transmission electron microscopy. Ausforming has been found to accelerate bainite transformation at 573 K. A characteristic microstructure consisting of blocky bainitic laths and retained austenite is observed

THE grain size of the ultra-strong, ausformed steels is probably an important factor in their strength and ductility, but it is yet uncertain. The structures are so fine and complex that even the electron microscope has not hitherto revealed the grain structure clearly.

Lattice defects are introduced into stable austenite (β) by hot rolling up to 70% (in one pass) in a temperature range between 900 > TAF > 340 °C (ausforming (AF)). The changes in microstructure, thermal transformation behavior, as well as normal and anomalous properties in stress-, strain-, and temperature-space were studied.
