PDF 4 ALLVAC 718 Plus Superalloy for Aircraft Engine.

The objective of all these programs is to develop an alloy with the following characteristics: 55C temperature advantage based on the LarsonMiller, timetemperature parameter Improved thermal stability equal to Waspaloy at 704C Good weldability at least intermediate to 718 and Waspaloy alloys www.intechopen.com ALLVAC 718 Plus Superalloy for Aircraft Engine Applications 85 Minimal.

Grain Boundary Engineering of Allvac 718Plus for Aerospace.

Allvac718Plus alloy a newly developed derivative of 718 alloy has been shown to have a higher temperature capability by about 55oC than the 718 parent alloy 2 that is largely due modifications to its chemistry. Relative to the parent alloy, 718Plus contains a higher Al/Ti

ALLVAC 718 Plus Superalloy for Aircraft Engine Applications

ALLVAC 718 Plus Superalloy for Aircraft Engine Applications 79 still used in industrial turbines, but were later replaced by Waspaloy and Astroloy as stress and temperature requirements increased. These alloys were turbine blade alloys with a suitably modified heattreatment for discs. However, blade material is designed for creep,


melting trials, ATI Allvac has developed a new alloy, Allvac 718Plus, which offers a full 55C temperature advantage over alloy 718 1214. The alloy maintains many of the desirable features of alloy 718, including good workability, weldability and moderate cost. The alloy
