Progress Toward a Deformation Map for Fine Grain Alloy 718 Billet Open
A deformation map, or microstructural map, has been developed for Alloy 718.This map defines microstructures that are obtained as a function of temperature, strain rate, and strain when forging fine grain Alloy 718 billet.The map delineate…
Factors Affecting Delta Phase Precipitation and Growth at Hot Work Temperatures for Direct Aged Inco 718 Open
The billet conversion and forge practise of DA 718 employs temperatures in the range where delta phase may precipitate, may agglomerate, or may redissolve depending on the prior microstructure, time at heat, and chemical homogeneity.The ne…
TMP: Its Effect on Turbine Hardware Open
The authors consider TMF as the deliberate mating of the deformation and heat treat processes to achieve specific mechanical property goals.The conception and birth of TMP is traced from the early 1950's involving the 16-25-6 and ~-286 all…
