  • Process for improving the hot workability of aluminum-magnesium alloys
    Patent number: 4066480
    Abstract: A method of heat treating aluminum alloys of the aluminum-magnesium type to improve the hot workability of the alloys which consists essentially of homogenizing the alloys at a temperature from 950.degree. to 1050.degree. F for from 2 to 12 hours and slowly cooling said alloys to at least 800.degree. F at a rate of less than 100.degree. F per hour.
    Type: Grant
    Filed: August 11, 1976
    Date of Patent: January 3, 1978
    Assignee: Swiss Aluminium Ltd.
    Inventors: Damian V. Gullotti, William S. Fayard, Wiley W. Wedgeworth
  • Duplex process for improving the hot workability of aluminum-magnesium alloys
    Patent number: 4066476
    Abstract: A method of heat treating aluminum alloys of the aluminum-magnesium type to improve the hot workability of the alloys which comprises homogenizing the alloys at a first temperature from 950.degree. to 1050.degree. F for from 2 to 12 hours, cooling the homogenized alloys to a second temperature, further homogenizing said alloys at said second temperature where the second temperature is from 750.degree. to 900.degree. F for from 2 to 12 hours and optionally finally slowly cooling said alloys to at least 800.degree. F at a rate of less than 100.degree. F per hour.
