Effect of Cooling Rate under Quenching on the Structure and Properties of Sheets Made of High-Tech Alloy V-1341 of the Al-Mg-Si System

摘要

Phase transformations for alloy V-1341 of the Al-Mg-Si system under cooling from quenching temperature are investigated by differential scanning calorimetry and by transmission electron microscopy. An isothermal phase transformation diagram is generated by a design-experiment method. It is shown that the proposed method developed according to quenching factor theory makes it possible to predict reliably the dispersion hardening as a function of cooling rate for sheets made of alloy V-1341.
