1.Select temperature of suitable interval and check their properties.

2. Phase diagrams of both the alloys and find temperature

In general, the higher temperatures will shorten the life of weldment . The temperature ranges are depending on welding process also disimlar metals properties. The greater the number of thermal cycles will be lead to greater the damage. The metal life is shortened by longer times at temperature.

For more information, please see the guidelines for welding dissimilar metals which is attached.

1.according to materials phase diagrams to select heat treatment of adjusting properties.

2.according to residual stress of joint to select heat treatment to reducing residual stress .

Good afternoon, Prabakaran M P!

1. One of the ways out can be done by heat treatment on samples with testers, followed by control of the microstructure.

2. According to the transformation phase diagrams, select the most suitable heat treatment for the steels or alloys you are using.

2. Use "Qform" software for preliminary estimation of grain size (but this method requires confirmation) after simulating heat treatment.

Kindly clarify the question. Do you mean the preheat temperature or the temperature during diffusion welding (bonding) or anything else?

All depends on the materials being used. You should look for the phase diagram, microstructure analysis, choosing proper heat treatment procedure etc. Lowering the residual stress is very important. Long time application of high temperature can shorten the life as well.

I would suggest to use 'qform' software for further analysis.

I'm new in simulation softwares and I'm looking for the software QForm to conduct some analysis in my research.

I would like to know where I can find the software to download?

Rostislav Podolskyi do you have the instalation setup of this software to share with me?

Thanks in advance!
