To eliminate the problem of caustic embrittlement use sodium phosphate instead of sodium carbonate as softening reagents. Adding tannin or lignin to boiler water blocks the hair-line cracks and prevents infiltration of NaOH into these areas. Adding Na2SO4 to boiler water also blocks the hair-line cracks.
Embrittlement is a loss of ductility of a material, making it brittle. Various materials have different mechanisms of embrittlement.
Grain boundary embrittlement is a phenomenon where materials become brittle due to the segregation of impurities or the presence of defects at the boundaries between individual grains in a polycrystalline material. This can weaken the material and reduce its ability to deform plastically, making it more susceptible to fracture. Embrittlement can occur due to factors such as intergranular fracture, stress concentrators, and environmental factors.
Caustic acid, also known as sodium hydroxide, is commonly used in various industrial processes such as manufacturing, cleaning, and chemical synthesis. It is used in industries like paper production, wastewater treatment, and soap making. Additionally, it can be found in household products like drain cleaners and oven cleaners.
Another name for caustic soda is sodium hydroxide.

caustic embrittlement
caustic embrittlement (′kö·stik im′brid·əl·mənt) (metallurgy) Intercrystalline cracking of steel caused by exposure to caustic solutions above 70°C while under tensile stress; once common in riveted boilers. Also known as caustic cracking.
It may lead to caustic embrittlement.

caustic soda is used to eliminate Mercaptans from hydrocarbons (GPL, Kerosene, ...).it is used also as an injection the desalter (crude distillation unit) to raise PH (reduce corrosion).
Embrittlement is a loss of ductility of a material, making it brittle. Various materials have different mechanisms of embrittlement.
There is no such thing as caustic acid - caustic soda - YES. Caustic potash - YES - but not caustic acid

Congress could eliminate gerrymandering by issuing each representative districts that are of equal size and mostly square. However, I do not believe that congress would want to eliminate the problem. It certainly is a problem for us, but unfortunately for the representatives, it isn't. There definitely should be something done about it, though.
