"Sorry Guys for pushing this off in the wrong direction.
Nabeel had asked if weldability on stainless was improved by oxidizing the surface"
There is also a mention of elevated temperatures in the original post besides oxidizing the surface.Since I do not know the temperatures so...
Adding to what GTAW said earlier. If corrosion is a problem then use extra low carbon gardes (ELC). Stainless steel has already much less carbon content,making it furthur less will give us extra low carbon grades specified as 304L or 316L. This minimize the chance of sensitizing the stainless...
Thank you for your response.
Please find attached the snapshot from the Welding metallurgy book by Sindo Kou.
The slope of a tangent to the equilibrium liquidus line which partitions the planar solidification front from the columnar or dendritic growth region is being given in terms of...
Thank you for the recommendation Dhurjati Sen.
I just wanted to ask that how chemical composition influences microstructure. Lets say an Al-Cu system, given two alloys one containing 3 percent copper and other 4 percent copper. Which will have higher tensency for dendritic growth?
Thank you
Hello all.
I have a question about the the relationship between the amount of solute content in the molten pool and the degree of constitutional suoercooling. Is there any way that we can say that solute content influences the type of microstructure we get in the fusion zone?
Thanx in advance
Hello all.
Recently working on D406 Steel. Its a very high strength steel. I do not find much data in ASTM standards about this material. Does any one has any idea what is the origin of this particular steel? Chinese, German or Japanses?
Best regards

Hello all, i am new to this metallurgy forum. I am involved in materials work.
I have a question and shall be greatly thankful if anyone rsponds.
What are the yield strength and hardness values of 7075-T61?
I googled but only found tensile strength.
Thank you all
Hi all, can anyone please tell me what is the basic difference between solid solution alloying and precipitation hardening? Which and these methods can be used for strengthening of various commonly used materials like low carbon steels, austenitic stainless steels and 2000 series of aluminium...
