Abstract
Using an extrapolation of tensile data obtained under varying amounts of hydrostatic compression to positive hydrostatic pressure (hydrostatic tension), the cohesive strength of a low-carbon steel (0.03% C) has been determined. These preliminary results indicate a value of 54.6 kg/mm2, somewhat lower than obtained by other investigators. Increased strength with decreasing temperature occurs and is consistent with other observations.
Résumé
La force de cohésion d' un acier à faible 'carbone (0,03% C) a été déterminée par extrapolation des données de traction, obtenues pour diverses valeurs de la compression hydrostatique à une pression hydrostatique positive (tension hydrostatique). Ces résultats préliminaires indiquent une valeur de 54,6 kg/mm2, valeur quelque peu inférieure à celles obtenues par d' autres chercheurs. On constate un accroissement de la force pour une diminution de la température et ceci est conforme à d' autres observations.
Zusammenfassung
Durch Extrapolation vonZugspannungsdaten, welebe unter verschiedenen hydrostatischen Druücken erhalten wurden, auf den Positivwert des hydrostatischen Druckes (hydrostatische Dehnung), wurde die Kohasionsfestigkeit von kohlenstoffarmen Stahl (0.03% C) bestimmt. Die vorläufig erhaltenen Ergebnisse ergeben einen Wert von 54,6 kg/mm2, der etwas niedriger liegt, als die bisher von anderen Forschern erhaltenen Werte.
In Uebereinstimmung mit anderen Beobachtungen nimmt mit fallender Temperatur die Festigkeit zu.
