Analysis of forging process properties of common titanium

There are two reasons first,the alloy has high plasticity and low deformation resistance in the phase region Long forging time is conducive to improving productivity; second,the billet for ingot opening is mainly used for forging,and its microstructure can be improved after forging with large deformation degree,which will not affect the properties of forgings,so the process with high productivity is selected.Author Andrey BelyakovInfluence of Thermomechanical Treatments on the The heat treatable aluminium alloy AA2219 is subjected to mechanical stress relieving by way of cold deformation after solution treatment to relieve the quenched in stresses as thermal stress relieving is not possible due to the requirement of higher temperature than the ageing temperature.Cold deformation prior to aging has also been found to yield improved strength.CiteSeerX Improved Microstructure and Properties of 6061 CiteSeerX - Document Details (Isaac Councill,Lee Giles,Pradeep Teregowda) INTRODUCTION input is reduced to 25 percent.This process may provide a method to weld aluminum alloys without filler metal addi- AS one of the most commonly used heat-treatable alumition and to generate positive effects on productivity,cost,and num alloys,6061 is available in a wide range of structural weld quality.
