EFFECT OF TEMPERATURE ON DELAYED FRACTURE OF ALUMINUM ALLOY 2024 IN THE PRESENCE OF LIQUID ZING AMALGAM

摘要

Delayed fracture studies were conducted on aluminum alloy 2024 over a temperature range of 35 to 190° F, The alloy was solution treated at 920° F for one hour, cold water quenched, and then artificially aged at 375° F for four hours. Specimens were heated to desired temperatures in a liquid test bath. The specimens were then stressed to selected levels and were wetted using a liquid 2% zine amalgam. Times to failure at different temperature levels were then determined.
