| Popis: | A steel with low mass contents of carbon (0.04 %) was quenched and aged at temperatures between 60 and 200°C. The increase in yield stress due to these aging treatments and other mechanical properties were analyzed. A rather direct correlation of results from internal friction with those for yielding exists. The precipitates which form during aging at the lowest temperatures are equally capable of improving the yield stress. Thus it is possible to improve the properties by modified bake-hardening. Comparisons with literature confirmed that the aging procedures influence the kinetics of precipitation and the resulting strength increase: intermediate aging at room temperature before the proper aging treatment are of advantage. |
