Cast Aluminum Preforms
Cast Aluminum Preforms
Dec 14, 2008
Q: I am looking for information, both technical and statistical, on the status of cast aluminum preforms for forgings. I found scattered references online, but not much real information. What is the status of this technology?
Highvalue automotive wheels are among the most recognizable applications for forged magnesium alloys
Forging Magnesium Alloys
Dec 14, 2008
Some tips for those just starting to forge magnesium alloys Forging pressure is no problem Avoid cracking Use hydraulic presses or crank presses
Transverse defects are common in upset forgings of stainless steel
Ask Jim: Transverse Defects in Steel
Dec 14, 2008
One defect seems to reoccur in upset forging, and in forgings produced at slow speeds in hydraulic presses Stainless ...but in 4140 too? Watch for lateral shearing
quotFor larger parts it may be necessary to install one or more fans to speed up the aircooling cycle and in turn to ensure a proper hardness response This may be especially important for forgings that have section sizes larger than about 25 in thick This may also reduce the length of the conveyors needed to ensure sufficiently low temperatures before entering the final boxesquot

Press Forging Die Failures
Apr 20, 2008
Q: We press forge a shaft gear to close tolerances and we use a shrink ring assembly for the bottom die. How can we address interference?
Centerline Micro-Cracking
Apr 20, 2008
Q: We’ve found some microcracking in billets forged on a steam hammer. The upset ratio is 2.5 to 1, and our forging temperature is 1,800°-2,200ºF.
Trimming Ti-6Al-4V and PH stainless grades
Feb 17, 2008
Q: Some time ago you responded to our problems with trimming Ti grades. Some of your ideas have helped, but we are still having some problems that just do not go away especially with the PH stainless grades. Do you have any other ideas?
